In the Court of Appeals of Georgia A24A0749. KATHY BOONE et al v. VASCULAR SURGICAL ASSOCIATES, P.C., et al.

DILLARD, Presiding Judge.

Paula Thacker suffered debilitating injuries and ultimately died following

medical treatment for a series of small strokes. Thereafter, Kathy Boone—Paula’s

daughter—filed a medical-malpractice suit against numerous individuals and

companies, including Vascular Surgical Associates, Northwest Neurology, P.C., Dr.

Sandy McGaffigan, Dr. Arun Chervu, and Dr. Gary Jacobson.1 The case proceeded

to a jury trial, after which a verdict was entered in favor of the appellees. Boone

appeals, arguing the trial court erred by (1) permitting an unqualified defense expert

For

the following reasons, we affirm.2

Viewing the evidence in the light most favorable to the jury’s verdict,3 the

record shows that, in 2016, Thacker was diagnosed with carotid artery disease in her

left and right carotid arteries. Generally, the symptoms of the disease are “some sort

of stroke-like event that could be related to those carotids[,]” but at the time she was

diagnosed, Thacker was asymptomatic. Nevertheless, as a preventative measure,

Thacker was prescribed aspirin and a high-dose statin medication.

On March 25, 2018, Thacker began feeling numbness on the right side of her

face, and Boone took her to Wellstar Paulding Hospital. Once they arrived, Thacker

was evaluated by a doctor who determined she had suffered a series of “small

See Court of Appeals of the State of Georgia, Oral Argument, Case No. A24A0749 (May 1, 2024), available at https://vimeo.com/942076478. Of note, two appellee briefs were submitted in this case, one by VSA, Dr. Chervu, and Dr. Jacobson, and another by Northwest Neurology and Sandy McGaffigan. 3 See Amu v. Barnes, 286 Ga. App. 725, 725 (650 SE2d 288) (2007) (“[When] a jury returns a verdict, the same must be affirmed on appeal if there is any evidence to support it, and the evidence is to be construed in a light most favorable to the prevailing party with every presumption and inference in favor of sustaining the verdict.” (punctuation omitted)). 2 strokes[,]”which can cause damage to parts of the brain. As a result, on March 26,

2018, she was transferred to Cobb Hospital for a vascular consult. Later that day,

Thacker was seen by Dr. McGaffigan, a neurologist, as well as other

physicians—including a cardiologist and a vascular surgeon. Following these

evaluations, Thacker was diagnosed with “crescendo TIAs,” which is a “situation

where a patient is having multiple events more and more often.” Thacker was then

placed on an “IV or intravenous heparin infusion drip.” And that night, even though

Thacker was taking heparin, aspirin, and was receiving IV fluids, she suffered an

episode of right facial drooping, numbness in her right hand, and had difficulty

speaking.

Initially, Dr. Jeffrey Winter—a vascular surgeon—scheduled Thacker to

undergo a carotid endarterectomy.4 But the next day, on March 27, 2018, Dr.

Chervu—another vascular surgeon—evaluated Thacker and determined that, instead,

she needed to have a transcarotid artery revascularization (“TCAR”) procedure,

which is a technique by which a metal stent is placed in the patient’s carotid artery.

4 Carotid endarterectomy is “a procedure to treat carotid artery disease.” Mayo Clinic, https://www.mayoclinic.org/tests-procedures/carotid-endarterectomy/ about/pac-20393379 (Last visited July 30, 2024). 3 And the next morning, on March 28, 2018, Chervu performed the TCAR procedure.

Relevant here, Chervu admitted that he deviated from his medical training by waiting

to administer Plavix5 to Thacker until approximately three hours after the procedure,

rather than beforehand. And in the context of this case, this practice involved

combining aspirin and Plavix, and is referred to as dual-antiplatelet therapy

(“DAPT”).6 Chervu did not administer this therapy to Thacker prior to surgery

because he was concerned about combining these medications due to the heightened

risk of bleeding.

Shortly after the procedure, Dr. Chervu told Boone he was concerned Thacker

might have experienced a new stroke because her blood pressure repeatedly spiked

during surgery. But the doctors who assessed Thacker that afternoon concluded she

had not suffered a new stroke. Additionally, Chervu asked Dr. McGaffigan for help

5 Plavix is “used alone or together with aspirin to lessen the chance of a heart attack or stroke. ” M a y o C l i n i c , h t t p s : / / w w w . m a y oclinic.org / drugs-supplements/clopidogrel-oral-route/description/drg-20063146 (Last visited July 30, 2024). 6 Dual antiplatelet therapy “with aspirin and oral P2Y inhibitors remains the cornerstone of therapy for patients with acute coronary syndrome (ACS).” Mayo Clinic, https://www.mayoclinicproceedings.org /article/S0025-6196(22)00127-6/fulltext (Last visited July 30, 2024) (footnote omitted). 4 evaluating Thacker because she was a neurologist; and after doing so, she likewise did

not believe Thacker had suffered another stroke. Thacker’s condition improved

throughout the day, and when Chervu evaluated her at 6:30 p.m., she was more alert,

her speech had improved, and she had increased range of motion in her right arm.

Nevertheless, Thacker’s condition worsened over the next several hours, and

by 8:00 p.m., the nurse on duty found her unresponsive. The nurse immediately

performed an “NIH Stroke Scale assessment,” which required him to assign a score

to various categories of symptoms. Thacker’s total score indicated that she had

suffered a “severe stroke.” The nurse also calculated a “Glasgow Coma Score,” and

found that Thacker’s score had fallen from 15 to 10, which suggested she was

experiencing neurological problems. Then, around 8:55 p.m., the nurse called Dr.

Jacobson—who was the vascular surgeon on call—to tell him about the situation. But

according to Jacobson, during the call, he was not informed of the scores Thacker

received on the foregoing scales or anything else suggesting the stent implanted in her

artery was blocked. After Thacker was released from the hospital, her symptoms got

“worse and worse over time”; and tragically, she passed away.

5 Thereafter, on December 19, 2018, Thacker—by and through her next friend,

Boone—filed a malpractice suit against VSA, Dr. Chervu, and Dr. Jacobson.7 Boone

later amended her complaint to include medical-malpractice claims against Northwest

Neurology and Dr. McGaffigan.8 On February 11, 2022, Boone filed a second

amended complaint “in anticipation of the upcoming trial . . . .” Relevant here, Boone

alleged that Chervu was negligent in failing to administer DAPT to Thacker prior to

the TCAR procedure. Following protracted discovery, the case proceeded to trial, and

the jury rendered a verdict in favor of the appellees.
