Surgical Management of Pediatric renin-mediated Hypertension seCONDARY TO RENAL ARTERY OCCLUSIVE DISEASE AND ABDOMINAL AORTIC COARCTATION
Renovascular hypertension (RVH) associated with renal artery and abdominal aortic narrowings is the third most common cause of pediatric hypertension. Untreated children may experience major cardiopulmonary complications, stroke, renal failure and death. The impetus of this study was to describe the increasingly complex surgical practice for such patients with an emphasis on anatomic phenotype and contemporary outcomes following surgical management, as a means of identifying those factors responsible for persistent or recurrent hypertension necessitating reoperation.

Early vascular imaging and key system strategies expedite carotid revascularization after transient ischemic attack and stroke
International guidelines recommend carotid revascularization within 14  days for patients with a symptomatic transient ischemic attack (TIA) or stroke event. However, significant delays in care persist, with only 9% of outpatients and 36% of inpatients in Ontario meeting this target. The study objective was to explore the influence of health system factors on carotid revascularization timelines.

Protamine use in transcarotid artery revascularization is associated with lower risk of bleeding complications without higher risk of thromboembolic events
Recent studies have found that transcarotid artery revascularization (TCAR) is associated with lower risk of stroke or death compared with transfemoral carotid artery stenting but higher risk of bleeding complications, presumably associated with the need for an incision. Heparin anticoagulation is universally used during TCAR, so protamine use may reduce bleeding complications. However, the safety and effectiveness of protamine use in TCAR are unknown. We therefore evaluated the impact of protamine use on perioperative outcomes after TCAR in the Vascular Quality Initiative TCAR Surveillance Project.

Association of upper extremity and neck access with stroke in endovascular aortic repair
Upper extremity and neck access is commonly used for complex endovascular aortic repairs. We sought to compare perioperative stroke and other complications of (1) arm/neck (AN) and femoral or iliac access versus femoral/iliac (FI) access alone, (2) right- versus left-sided AN, and (3) specific arm versus neck access sites.

Patient risk factors associated with embolic stroke volumes after revascularization
Previous research has shown that subclinical, microembolic infarcts result in long-term cognitive changes. Whereas both carotid endarterectomy (CEA) and carotid artery stenting (CAS) have potential for microembolic events, CAS has been shown to have a larger volume of infarct. We have previously shown that large-volume infarction is associated with long-term memory deterioration. The purpose of this study was to identify independent risk factors that trend toward higher embolic volumes in both procedures.

Stroke rate after endovascular aortic interventions in the Society for Vascular Surgery Vascular Quality Initiative
The stroke rate after endovascular aneurysm repair (EVAR), particularly complex EVAR such as fenestrated EVAR (FEVAR) and chimney EVAR (chEVAR), is not well defined. Whereas stroke is a well-established risk of thoracic endovascular aortic repair (TEVAR), the impact of procedural characteristics on stroke remains unclear. Therefore, we characterized the risk of stroke after endovascular aortic interventions in the Vascular Quality Initiative database and identified procedural characteristics associated with stroke.

Individual results may vary
In June of 1986, I arrived at the University of Cincinnati, eager to begin my vascular fellowship with Dick Kempczinski, a rising star in the academic vascular community. My arrival coincided with the publication of a groundbreaking, and somewhat sobering, review of the outcomes of carotid endarterectomy in the Cincinnati community, authored by Dick and Tom Brott.1 They found a disturbing stroke rate of 5.1% and mortality of 2.3%, with no statistically significant difference based on the specialty of the operating surgeon —by implication, all specialties were performing the procedure equally poorly.

Frailty as measured by the Risk Analysis Index is associated with long-term death after carotid endarterectomy
The role of carotid endarterectomy (CEA) continues to be debated in the age of optimal medical therapy, particularly for patients with limited life expectancy. The Risk Analysis Index (RAI) measures frailty, a syndrome of decreased physiologic reserve, which increases vulnerability to adverse outcomes. The RAI better predicts surgical complications, nonhome discharge, and death than age or comorbidities alone. We sought to measure the association of frailty, as measured by the RAI, with postoperative in-hospital stroke, long-term stroke, and long-term survival after CEA.

Carotid Endarterectomy Remains Safe in High-Risk Patients
Carotid endarterectomy (CEA) is a proven intervention for stroke risk reduction in symptomatic and asymptomatic patients. High-risk patients are often offered carotid stenting to minimize risk and to optimize outcomes. As a referral center for high-risk patients, we sought to evaluate and to analyze our experience with high-risk CEA patients.

Defining the threshold surgeon volume associated with improved patient outcomes for carotid endarterectomy

Concomitant carotid endarterectomy and cardiac surgery does not decrease postoperative stroke rates
We examined the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database to evaluate the association of combined carotid endarterectomy (CEA) and coronary artery bypass grafting (CABG) with postoperative outcomes.

Drain placement confers no benefit after carotid endarterectomy in the Vascular Quality Initiative
Whereas bleeding complications requiring a return to the operating room (OR) after carotid endarterectomy (CEA) are infrequent (1%), they are associated with an increased 30-day combined postoperative stroke or death rate. Drain placement after CEA varies among vascular surgeons, and there are limited data to support the practice. The goal of this study was to evaluate factors leading to drain placement and the effect of drains on postoperative outcomes including return to OR for bleeding, stroke, and death.
