April 28, 2022
BARRON, Chief Judge. This appeal is from a grant of
summary judgment against Eulalia López-Ramírez ("López"), in the
medical malpractice suit that she, joined by her daughter, brought
under Puerto Rico law in the United States District Court for the
District of Puerto Rico. The suit seeks recovery in connection
with the brain surgery that was performed on López to alleviate
her facial spasms. We affirm.
I.
We begin with a description of the undisputed facts and
the procedural history. We then provide some of the relevant legal
background to set the stage for the analysis to follow.
A.
López had been suffering for approximately eighteen
years from facial spasms -- specifically, "right hemifacial
spasms." She had stopped responding to Botox treatment.
To address the spasms, López visited a neurosurgeon,
Dr. Maria M. Toledo González ("Dr. Toledo"), on September 29,
2015. Dr. Toledo recommended surgery after a "Brain MRI scan"
revealed that a blood vessel abutted López's right facial nerve.
The surgery would involve entering López's skull using a procedure
known as a "right retrosigmoid craniotomy" and then surgically
moving the offending blood vessel away from the nerve, or
"decompressing" the nerve, in a process known as "microvascular
decompression."
- 3 -
López consented to having the surgery performed at
Hospital HIMA (the "Hospital").1 During the surgery, which
occurred on January 26, 2016, Dr. Toledo used a process the parties
described as "neuromonitoring" to determine, using equipment,
whether her manipulation of the nerves and blood vessels was
causing any irritation or damage to the nerves.
Later that day, after the surgery had been completed,
López was "[b]arely able to raise [her] eyebrow" and could not
fully close her eye. Her condition worsened until, a few days
later, Dr. Toledo confirmed that López could "not hear anything"
in her right ear, had full right facial paralysis, and was "in a
wheelchair due to lack of balance." Further testing revealed
greater damage.
B.
On December 23, 2016, López and her daughter brought
this lawsuit in the District of Puerto Rico against Dr. Toledo,
the Hospital, and various other defendants. The operative
complaint claimed that the defendants failed to provide López "with
1The record does not contain López's written consent to
the surgery, and although the parties' experts mention a consent
form, they dispute whether that document constituted evidence of
an informed consent to the surgery. Although the plaintiffs
referred to an alleged inadequacy in the consent in the joint
pretrial conference report, they did not advance any argument
concerning the consent in their briefing in opposition to
Dr. Toledo's motions to exclude their expert testimony and for
summary judgment.
- 4 -
adequate neurological evaluation and treatment during her surgery
and stay in the hospital" or the "consultations" and "treatments"
necessary to "avoid a massive stroke," and that these failures
"constituted gross negligence." The complaint further claimed
that the defendants "deviat[ed] from accepted medical practices"
by "performing surgery without identifying, isolating and
protecting the nerve and vascular tissue in the affected area," by
"fail[ing] to timely diagnose the devastating neurological damage
in process," and by "fail[ing] to provide adequate monitoring in
the process to identify the risks and multiple perforations to the
cerebral artery."
The complaint claimed that the defendants' negligence
in providing medical care to López made them liable to her and her
daughter under Puerto Rico Laws title 31, Sections 5141 and 5142.
The complaint sought economic and non-economic damages, including
for López's "severe physical and emotional pain and suffering,"
and her daughter's "severe emotional suffering."2
C.
To establish a "prima facie case" of negligence under
Puerto Rico Laws title 31, Section 5141, the plaintiffs must
2Because the District Court, at the plaintiffs' request,
dismissed all claims against all defendants except for Dr. Toledo
and the Hospital, those two parties were the only defendants that
remained at the time that the District Court issued the order that
the plaintiffs appeal. We hereafter use the term "defendants" to
refer to only Dr. Toledo and the Hospital.

establish: "(1) the duty owed (i.e., the minimum standard of
professional knowledge and skill required in the relevant
circumstances), (2) an act or omission transgressing that duty,
and (3) a sufficient causal nexus between the breach and the
claimed harm." Cortés-Irizarry v. Corporación Insular De Seguros,
111 F.3d 184, 189 (1st Cir. 1997). With respect to a negligence
claim that alleges medical malpractice, "Puerto Rico holds health
care professionals to a national standard of care." Id. at 190.
In addition, for such claims, "Puerto Rico law presumes that
physicians exercise" the reasonable level of care. Id. The
plaintiffs "bear[] the burden of refuting this presumption."
Rolon-Alvarado v. Municipality of San Juan, 1 F.3d 74, 78 (1st
Cir. 1993). Thus, " a plaintiff bent on establishing a breach of
a physician's duty of care ordinarily must adduce expert testimony
to limn the minimum acceptable standard and confirm the defendant
doctor's failure to meet it." Cortés-Irizarry, 111 F.3d at 190.
Against this legal backdrop, the plaintiffs proposed to
introduce at trial the testimony of "an expert in neurology,"
Dr. Allan Hausknecht ("Dr. Hausknecht"), to support their claim
that there had been a breach of the applicable standard of care
during López's surgery. In addition, the plaintiffs "reserve[d]
the right to use as their own any expert witness announced by
defendants" in support of their negligence claims. The defendants
proposed in response to introduce the testimony of their own expert
- 6 -
witness: Dr. Ricardo H. Brau Ramírez ("Dr. Brau"), an "expert in
neurosurgery."
Federal Rule of Evidence 702 provides:
A witness who is qualified as an expert by
knowledge, skill, experience, training, or
education may testify in the form of an
opinion or otherwise if:
(a) the expert's scientific, technical, or
other specialized knowledge will help the
trier of fact to understand the evidence or to
determine a fact in issue;
(b) the testimony is based on sufficient facts
or data;
(c) the testimony is the product of reliable
principles and methods; and
(d) the expert has reliably applied the
principles and methods to the facts of the
case.
Fed. R. Evid. 702. In addition, Federal Rule of Civil Procedure 26
requires that a party seeking to admit expert witness testimony
must submit "a written report" that "must contain:"
(i) a complete statement of all opinions the
witness will express and the basis and reasons
for them;
(ii) the facts or data considered by the
witness in forming them;
(iii) any exhibits that will be used to
summarize or support them;
(iv) the witness's qualifications, including
a list of all publications authored in the
previous 10 years;
(v) a list of all other cases in which, during
the previous 4 years, the witness testified as
an expert at trial or by deposition; and
(vi) a statement of the compensation to be
paid for the study and testimony in the case.
Fed. R. Civ. P. 26(a)(2)(B).
- 7 -
The parties stated in a joint pretrial conference report
filed on July 12, 2018, that each side would produce an expert
report describing its respective expert's analysis. The
plaintiffs produced two reports from Dr. Hausknecht that purported
to describe his expert opinion and the basis for it.
The first of those reports set forth Dr. Hausknecht's
analysis of the surgery that had been performed on López by
Dr. Toledo. The report explained that it was Dr. Hausknecht's
opinion both that Dr. Toledo had failed to properly "isolate" and
"protect" López's nerves and blood vessels during the surgery and
that this failure caused her injuries. The second of those
reports, which was dated approximately one month after the first,
detailed the results of Dr. Hausknecht's own "comprehensive
neurological examination" of López, as well as her medical history
and post-surgical symptoms.
The defendants produced their own expert report from
their proposed expert, Dr. Brau. Dr. Brau's report explained that
it was his expert opinion that Dr. Toledo followed the applicable
standard of care despite the unfortunate surgical outcome.
A little over a year later, Dr. Toledo filed a motion
under Federal Rule of Evidence 702 and Federal Rule of Civil
Procedure 26(a)(2)(B) to "strike Dr. Hausknecht as an expert, or
at least his opinion that Dr. Toledo committed medical
malpractice." The Hospital joined that motion. Attached to the
- 8 -
motion as exhibits were both of Dr. Hausknecht's expert reports
and a full transcript of Dr. Hausknecht's deposition testimony.
The motion contended, among other things, that
Dr. Hausknecht's opinion in the report assumed negligence based
only on the negative outcome of the surgery and that his opinion
thereby relied on a "res ipsa loquit[ur]" theory of negligence.
As the District Court explained, that theory "is a torts doctrine
'providing that, in some circumstances, the mere fact of an
accident's occurrence raises an inference of negligence that
establishes a prima facie case.'" López Ramírez v. Grupo HIMA San
Pablo, Inc., No. 16-3192, 2020 WL 365554, at *5 n.2 (D.P.R. Jan.
22, 2020)(quoting Res Ipsa Loquitur, Black's Law Dictionary (11th
ed. 2019)). The motion asserted that Puerto Rico law has
foreclosed that theory of negligence in medical malpractice cases.
The motion thus contended that Dr. Hausknecht's testimony -- or,
at least, his opinion regarding Toledo's malpractice -- was
inadmissible pursuant to Federal Rule of Evidence 702.
The motion separately identified two additional reasons
to strike Dr. Hausknecht's "report and expected testimony," "or at
least his opinion that Dr. Toledo committed medical malpractice."
The motion argued first that Dr. Hausknecht's report did not
include the statement of his compensation required by Federal Rule
of Civil Procedure 26(a)(2)(B). The motion also argued that he
- 9 -
was not qualified to serve as an expert pursuant to Federal Rule
of Evidence 702 because he was "a neurologist, not a neurosurgeon."
Approximately two months later, following a final
pretrial conference, the District Court stated in a minute entry
that it entered on the docket that it was "incline[d] to hear the
testimony of [Dr. Hausknecht] out of the presence of the Jury
pursuant to [Federal Rule of Evidence] 104."3 But, the District
Court, without first having held such a hearing, then later issued
an opinion and order striking "[Dr.] Hausknecht's proffered expert
opinions regarding the standard of care and Dr. Toledo's alleged
negligence." López Ramírez, 2020 WL 365554, at *6.
The District Court explained in its opinion that it was
rejecting the defendants' contentions that Dr. Hausknecht's
opinions must be struck under Federal Rule of Civil Procedure 26
because Dr. Hausknecht failed to include in his expert report a
statement of his compensation and under Federal Rule of Evidence
702 because he was not qualified as an expert. Id. at *5. The
District Court nonetheless determined that Dr. Hausknecht's
proffered expert opinions concerning, respectively, the applicable
standard of care and Dr. Toledo's "deviation from" it must be
struck pursuant to Federal Rule of Evidence 702. Id. at *6. The
Federal Rule of Evidence 104 provides, "The court must
3
decide any preliminary question about whether a witness is
qualified . . . . In so deciding, the court is not bound by
evidence rules, except those on privilege." Fed. R. Evid. 104(a).
- 10 -
District Court also ruled that Dr. Hausknecht's deposition did not
salvage either of those opinions for purposes of Rule 702, because
the deposition was "equally unhelpful, reiterating that
Mrs. López's results 'can only be explained by improper procedure'
despite listing other causes for similar injuries." Id.
That same day, the District Court issued an order for
Dr. Toledo "to file a motion for summary judgment" within three
weeks. Dr. Toledo thereafter filed the motion, which the Hospital
joined. The plaintiffs contended in response that they could prove
their case even without Dr. Hausknecht's testimony as to his
proffered expert opinions, because they could rely on the testimony
of the defendants' expert, Dr. Brau. "In the alternative," the
plaintiffs requested that the District Court reconsider its prior
ruling striking Dr. Hausknecht's testimony and, "in the best
interest of procedural and substantive justice," allow Dr.
Hausknecht to testify to the opinions regarding the applicable
standard of care and Dr. Toledo's alleged negligence.
The District Court denied the plaintiffs' request for
reconsideration, granted Dr. Toledo's motion for summary judgment,
dismissed the plaintiffs' claims with prejudice, and entered
judgment in favor of all remaining defendants. See López
Ramírez v. Grupo HIMA San Pablo, Inc., No. 16-3192, 2020 WL
- 11 -
5351851, at *1, *6, *8 (D.P.R. Sept. 4, 2020). The plaintiffs
then filed this timely appeal of that summary judgment order.4
II.
We first address the plaintiffs' challenges to the
District Court Order striking Dr. Hausknecht's proffered opinions
under Federal Rule of Evidence 702. Because we find no merit to
those challenges, we then address the plaintiffs' separate grounds
for challenging the District Court's grant of summary judgment in
favor of the defendants.5
A.
As the Supreme Court of the United States explained in
Daubert v. Merrell Dow Pharmaceuticals, Inc., Federal Rule of
Evidence 702 assigns a "gatekeeping role for the judge" to
"ensur[e] that an expert's testimony both rests on a reliable
4The plaintiffs' appeal from the District Court's entry
of summary judgment against them permits us to consider their
challenge to the District Court's predicate order striking Dr.
Hausknecht's opinions. See Martínez-Serrano v. Quality Health
Servs. of P.R., Inc., 568 F.3d 278, 283 (1st Cir. 2009) (explaining
that when an appellant "designate[s] the final judgment in a case
as the appeal's object . . . such a notice of appeal is deemed to
encompass not only the final judgment but also all interlocutory
orders that merge into it").
5 The plaintiffs also appear to assert that the District
Court imposed "too severe of a sanction" by excluding Dr.
Hausknecht's opinions. But, even assuming that challenge is
sufficiently developed for us to consider, it has no merit, because
the District Court excluded Dr. Hausknecht's opinions pursuant to
Federal Rule of Evidence 702 and not as a sanction for the
plaintiffs' failure to comply with Federal Rule of Civil
Procedure 26.
- 12 -
foundation and is relevant to the task at hand." 509 U.S. 579,
597 (1993). "The focus, of course, must be solely on principles
and methodology, not on the conclusions that they generate." Id.
at 595. "So long as an expert's scientific testimony rests upon
'"good grounds," based on what is known,' it should be tested by
the adversarial process, rather than excluded for fear that jurors
will not be able to handle the scientific complexities."
Milward v. Acuity Specialty Prods. Grp., Inc. (Milward I), 639
F.3d 11, 15 (1st Cir. 2011) (internal citation omitted) (quoting
and citing Daubert, 509 U.S. at 590, 596).
"There is an important difference between what
is unreliable support and what a trier of fact may conclude
is insufficient support for an expert's conclusion." Id. at 22.
Thus, "[w]hen the factual underpinning of an expert's opinion is
weak, it is a matter affecting the weight and credibility of the
testimony -- a question to be resolved by the jury." Id. (quoting
United States v. Vargas, 471 F.3d 255, 264 (1st Cir. 2006)).
Nonetheless, "nothing in either Daubert or the Federal
Rules of Evidence requires a district court to admit opinion
evidence that is connected to existing data only by the ipse
dixit of the expert. A court may conclude that there is simply
too great an analytical gap between the data and the opinion
proffered." Gen. Elec. Co. v. Joiner, 522 U.S. 136, 146 (1997).
So long, that is, as that gap is not "of the district court's
- 13 -
making." Milward I, 639 F.3d at 22 (quoting Kennedy v. Collagen
Corp., 161 F.3d 1226, 1230 (9th Cir. 1998)).
"The party seeking to introduce the evidence has the
burden of establishing both its reliability and its relevance."
Milward v. Rust-Oleum Corp. (Milward II), 820 F.3d 469, 473 (1st
Cir. 2016) (citing Daubert, 509 U.S. at 593 n.10). "We review the
district court's decision to admit or exclude expert testimony for
abuse of discretion," reviewing "[p]redicate factual findings" for
"clear error" and "pure questions of law . . . de novo." Id.
at 472; see also Joiner, 522 U.S. at 146.
The District Court struck the proffered opinions of
Dr. Hausknecht on two independent grounds under Federal Rule of
Evidence 702. See López Ramírez, 2020 WL 365554, at *6. First,
the District Court ruled that the plaintiffs failed to meet their
burden to show that Dr. Hausknecht had provided sufficient support
for the standard of care that he identified as being applicable to
the surgery in question. Id. Second, the District Court concluded
that the plaintiffs failed to meet their burden to show that Dr.
Hausknecht supportably had explained the basis for his opinion
that Dr. Toledo had deviated from the applicable standard of care,
insofar as Dr. Hausknecht had identified one. Id. As we will
explain, the District Court did not abuse its discretion in ruling
that the plaintiffs failed to meet their burden to show that
Dr. Hausknecht's opinion that Dr. Toledo deviated from the
- 14 -
applicable standard of care during the surgery rested on more than
res ipsa loquitur, which is a theory of negligence that the parties
in this case agree is not one that the plaintiffs may rely upon
under Puerto Rico law. We thus need not address the District
Court's other ground for striking Dr. Hausknecht's testimony. Id.Dr. Hausknecht stated in his expert report that the
applicable standard of care required a neurosurgeon performing the
type of surgery at issue to "identify, isolate, and protect" the
nerves and blood vessels in the brain. But, the District Court
concluded, Dr. Hausknecht failed to "specify[] . . . why" the
"standard of care applicable to Mrs. López's case" was "not met."
Id.The District Court noted in so concluding that
Dr. Hausknecht in his report "acknowledg[ed] the 'textbook' nature
of the operative report," which was a written summary of the
operation that Dr. Toledo signed, and the "inherent risks of the
surgery." Id. Indeed, according to both experts' summary of that
operative report, Dr. Toledo found during the surgery that there
were multiple perforators -- or small arteries that supply blood
to the brain -- coming out of a larger artery, the Anterior
Inferior Cerebellar Artery (AICA), and that the facial nerve had
been irritated. Moreover, according to both experts' summary of
the operative report, Dr. Toledo, after finding as much, decided
- 15 -
not to decompress any contact points between the nerve and AICA,
to withdraw from the area, and to conclude the surgery.
The District Court then went on to explain that,
notwithstanding Dr. Hausknecht's description of the operative
report as "'textbook,'" Dr. Hausknecht did not "provide any data
to sustain or explain the conclusory finding that there was a
deviation from the standard of care." Id. Moreover, the District
Court determined that "[a]lthough Dr. Hausknecht's report state[d]
that he included copies of journal articles that" he stated "'may
be helpful,' he fail[ed] to name them or relate the content of
said publications to his assertion that Dr. Toledo was negligent."
Id. For these reasons, the District Court concluded that there
was "'simply too great an analytical gap' between the content of
the report and the opinion proffered." Id. (quoting Joiner, 522
U.S. at 146).
The plaintiffs do not identify any statement in
Dr. Hausknecht's report that undermines the District Court's
assessment. Dr. Hausknecht's report states that "[o]bviously,
damage to the[] perforators did occur secondary to some activity
during the surgery." But, the plaintiffs do not identify -- and
we do not see -- where in the report Dr. Hausknecht explains the
basis for concluding that there was a deviation from the standard
of care. There is instead only the conclusory statement that
- 16 -
"[t]hese structures were not properly identified, isolated and
protected."
For example, Dr. Hausknecht's report does not state that
Dr. Toledo touched a nerve or vessel that she should not have
touched, given the applicable standard of care. His report also
does not address whether or how Dr. Toledo could have avoided
manipulating any nerves or vessels. Nor does Dr. Hausknecht's
report reject the possibility, as Dr. Brau states in his competing
report, that this is a procedure in which "manipulation of the
blood vessels" cannot be avoided because "[t]his operation is
designed to mobilize blood vessels away from the facial nerve."
In sum, Dr. Hausknecht's report sets forth his opinion that
Dr. Toledo was not sufficiently careful with respect to
"structures" without specifying in what respect Dr. Toledo
manipulated a "structure" in a manner that deviated from the
standard of care that he had identified.
As the plaintiffs point out, Federal Rule of
Evidence 702 "has been interpreted liberally in favor of the
admission of expert testimony." Levin v. Dalva Bros., Inc., 459
F.3d 68, 78 (1st Cir. 2006). But, the plaintiffs have not
identified anything more in the record than the conclusory
statements Dr. Hausknecht made in his report that opined that
Dr. Toledo deviated from the standard of care -- statements that
- 17 -
do not attempt to describe the principles or methods by which he
reached that opinion.
Moreover, the plaintiffs do not develop any contention
that Dr. Hausknecht's deposition testimony -- which, we note, the
District Court also considered but found "equally unhelpful,"
López Ramírez, 2020 WL 365554, at *6 -- bridges the "analytical
gap" that the District Court identified between Dr. Hausknecht's
stated opinion in his report that there had been a deviation from
the standard of care and the basis for that opinion. Id. (quoting
Joiner, 552 U.S. at 146). On appeal, the plaintiffs refer to
Dr. Hausknecht's deposition only to show that he was qualified to
speak to the standard of care itself. But, the District Court did
not dispute that he was qualified to do so.6 See López Ramírez,
2020 WL 365554, at *5.
6 The plaintiffs did, after oral argument, submit a
letter pursuant to Federal Rule of Appellate Procedure 28(j) to
which they attached the publications that they contended
Dr. Hausknecht relied on when he stated in his report that various
articles he did not name "may be helpful in understanding [his]
final opinions and conclusions." The plaintiffs also included a
list of the titles and authors of these publications in their brief
to us on appeal. But, it remains the case that Dr. Hausknecht's
reference in his report to the unnamed articles does not mention
how those articles address the "analytical gap" between his
conclusion and the explanation for it that formed the basis for
the District Court's exclusion of his expert opinion. López
Ramírez, 2020 WL 365554, at *6 (quoting Joiner, 522 U.S. at 146).
The plaintiffs' brief to us on appeal and the post-argument letter
purporting to attach those unnamed articles do not do so either.
Nor did the plaintiffs attempt to do so in their brief in
opposition to Dr. Toledo's motion in limine to exclude
Dr. Hausknecht's testimony.
- 18 -
The plaintiffs do emphasize that Puerto Rico law permits
a party seeking to prove negligence in a medical malpractice case
to demonstrate disputed facts "by indirect or circumstantial
evidence." But, the plaintiffs fail to show how Dr. Hausknecht's
report provides any circumstantial or inferential basis for his
opinion that Dr. Toledo's actions manipulated "structures" in a
manner that deviated from the standard of care.
In sum, after reviewing the expert reports and the
arguments made to us regarding the record in this case and the
relevant law, we see no abuse of discretion in the District Court's
order excluding Dr. Hausknecht's expert opinion that Dr. Toledo
deviated from the applicable standard of care in performing the
surgery on López that is the predicate for her suit. See United
States v. Zannino, 895 F.2d 1, 17 (1st Cir. 1990). Thus, the
plaintiffs' challenge to the grant of summary judgment fails
insofar as it depends on a challenge to the District Court's
exclusion of the relevant opinions proffered by Dr. Hausknecht
pursuant to Federal Rule of Evidence 702.
B.
We turn, then, to the plaintiffs' contention that, even
if the District Court did not err in striking Dr. Hausknecht's
expert opinion regarding the deviation from the standard of care,
the District Court erred in granting summary judgment to the
defendants. "To defeat a motion for summary judgment, the
- 19 -
nonmoving party must demonstrate the existence of a trialworthy
issue as to some material fact," i.e., a fact that "potentially
could affect the suit's outcome." Cortés-Irizarry, 111 F.3d
at 187; see also Borges ex rel. S.M.B.W. v. Serrano-Isern, 605
F.3d 1, 5 (1st Cir. 2010). That requires that a plaintiff
"affirmatively point to specific facts" that do so. Feliciano-
Muñoz v. Rebarber-Ocasio, 970 F.3d 53, 62 (1st Cir. 2020) (quoting
McCarthy v. Nw. Airlines, Inc., 56 F.3d 313, 315 (1st Cir. 1995)).
Our review is de novo. Milward II, 820 F.3d at 472–73.7
1.
The plaintiffs rely for this contention in part on what
the expert report that the defendants themselves filed in support
of their expert, Dr. Brau, showed. The District Court determined,
however, that summary judgment was "proper even after reading Dr.
Brau's report in the light most favorable" to the plaintiffs.
López Ramírez, 2020 WL 5351851, at *7 (quotation marks and citation
omitted). We see no basis for ruling otherwise.
The District Court explained that, although "Dr. Brau's
report did not directly question or contradict Dr. Hausknecht's
standard of care . . . to identify, isolate, and protect nervous
The plaintiffs in their briefing to us on appeal do
7
not develop any independent argument as to why the District Court
erred in granting summary judgment to the Hospital in particular,
aside from citing to the general allegations contained in their
complaint. They have therefore waived any such argument. See
Zannino, 895 F.2d at 17.
- 20 -
tissue," Dr. Brau's report set forth the conclusion that there was
"not even a trace of evidence in the medical chart that Dr. Toledo
failed to identify, isolate, and protect the nervous tissue and
vascular structure in this case." Id. (emphasis and citations
omitted). The District Court further explained that, because the
plaintiffs' claim that Dr. Brau may have left certain opinions out
of his report was "speculative at best," that conclusion did "not
create a factual dispute for purposes of summary judgment." Id.(emphasis and citation omitted).
In response on appeal, the plaintiffs contend only that
"Dr. Brau's testimony and cross-examination[] will help the jury
to determine both the proper standards of care and the causal nexus
between Defendants' negligence and Plaintiffs' damages" and that
the District Court "erred" in rejecting that argument. But, we
are not persuaded.
Dr. Brau states in the report that "Dr. Toledo followed
the standard of care" and "took all precautions" to "minimize the
risks"; that "[i]t is highly improbable that direct surgical trauma
to the nerves or the brainstem occurred during surgery"; and that
there "is not even a trace of evidence in the medical chart that
Dr. Toledo failed to identify, isolate, and protect the nervous
tissue and vascular structure in this case." The plaintiffs do
not explain how or why Dr. Brau's testimony would, despite these
statements, lend support to their case. Nor do they identify any
- 21 -
statements in Dr. Brau's report that might support a finding that
there remains a material dispute as to whether there was a
deviation from the standard of care. See Tropiagas de P.R.,
Inc. v. Certain Underwriters at Lloyd's of London, 637 F.3d 53, 56
(1st Cir. 2011).
Indeed, Dr. Brau's report describes specific surgical
decisions that Dr. Toledo made that are consistent with Dr. Brau's
opinion that Dr. Toledo did not deviate from the standard of care.
For example, the report states that Dr. Toledo "altered the
dissection of the Facial Nerve" when "she was notified that some
electrical changes were recorded" and "stopped the mobilization
of" the blood vessel, the AICA, "when the nerve became irritated."
The report also states that "[n]o hemorrhage, rupture, or tear of
the perforators, AICA or the Vertebral Arteries occurred," and
that "[t]he estimated blood loss for the procedure" was "below the
average blood loss for this procedure." And, while Dr. Brau
reserved the right to "modify, alter, amend, or change" his
opinion, the plaintiffs have failed to point to any facts that
might demonstrate how Dr. Brau's testimony might change, let alone
whether such a change would support their case.

The plaintiffs' final ground for challenging the grant
of summary judgment in favor of the defendants relies on an
exception to the general rule "that in a medical malpractice case
- 22 -
under Puerto Rico law 'a factfinder normally cannot find causation
without the assistance of expert testimony.'" Martínez-Serrano v.
Quality Health Servs. of P.R., Inc., 568 F.3d 278, 286 (1st Cir.
2009) (quoting Rojas–Ithier v. Sociedad Española de Auxilio Mutuo
y Beneficiencia, 394 F.3d 40, 43 (1st Cir. 2005)). That general
rule rests on the understanding that "medical malpractice is a
field in which the issues tend to be scientifically driven and
more nuanced than in most tort cases," id., and that "Puerto Rico
law presumes that physicians exercise reasonable care." Cortés-
Irizarry, 111 F.3d at 190.
As the plaintiffs point out, we have recognized that
some medical malpractice cases brought under Puerto Rico law may
involve alleged conduct "sufficiently blatant or patent" to permit
a negligence claim to survive summary judgment without an expert
witness; in such cases, the nature of the alleged error in
treatment is such that "lay persons, relying on common knowledge
and experience, can legitimately recognize or infer negligence."
Rolon-Alvarado, 1 F.3d at 79. But, although the plaintiffs contend
that theirs is such a case, we cannot say that the District Court
erred in determining that the plaintiffs had not "proffer[ed]
evidence that Dr. Toledo's conduct was 'sufficiently blatant or
patent' that" a lay person "could infer that her negligence caused
Mrs. López's current state." López Ramírez, 2020 WL 5351851, at *8
(quoting Rolon-Alvarado, 1 F.3d at 79).

The plaintiffs do assert in arguing otherwise that even
Dr. Brau "agrees that [López]'s injuries resulted from the
surgical manipulations performed by" Dr. Toledo and that a jury
could, on its own, determine that those manipulations were of the
avoidable and negligent kind. But, insofar as the plaintiffs mean
to argue that Dr. Brau's report sets forth an expert opinion that
Dr. Toledo performed the surgery negligently, it does not.
Dr. Brau did state in the report that Dr. Toledo's
"[m]anipulation of [the] AICA or its perforator[] vessels could
have trigger[ed] [a] vasospasm," which could have created an
interruption in blood flow and "eventually evolv[ed] into an
infarction," or tissue death. But, Dr. Brau also stated in that
same report that this "manipulation of the blood vessels" could
not "be avoided" because the "operation is designed to mobilize
blood vessels away from the facial nerve." So, Dr. Brau's report
does not indicate that such manipulations were of the avoidable
kind that the plaintiffs, implicitly, contend that he agreed that
they were.
Moreover, nothing in Dr. Brau's report provides support
for the plaintiffs' assertion that Dr. Toledo's conduct in
performing the surgery was so patently negligent that no expert
opinion to that effect is needed for their negligence claims to be
able to survive summary judgment. And, finally, we see no basis
for concluding that a "lay" juror "relying on common knowledge and
- 24 -
experience" can "infer," Rolon-Alvarado, 1 F.3d at 79, either that
the manipulations caused the injuries or, insofar as they did,
that they were the product of a deviation from the applicable
standard of care (even assuming that standard to be one that would
require that Dr. Toledo "identify, isolate, and protect the
nervous tissue and vascular (circulation) in the affected area").
Finally, insofar as the plaintiffs mean to rest their
contention that the exception recognized in Rolon-Alvarado should
apply on their allegation in their complaint "that Defendants were
'grossly negligent' because they did not provide Mrs. López with
adequate neurological evaluation and treatment during her surgery
and stay" at the hospital, and failed to provide the treatments
"'required to diagnose and/or avoid a massive stroke,'" they are
wrong to do so. Without more, these "mere allegations are not
entitled to weight in the summary judgment calculus." Borges, 605
F.3d at 3.
III.
The judgment of the District Court is therefore
affirmed.
