Multi-institutional patterns of clopidogrel response among patients undergoing transcarotid artery revascularization.

Objective: Current guidelines recommend dual antiplatelet therapy (DAPT) in patients undergoing carotid artery stenting. The most common DAPT regimen is aspirin and clopidogrel, a P2Y12 receptor antagonist; however, the prevalence of clopidogrel resistance (CR) in patients undergoing percutaneous coronary interventions may exceed 60%. Few studies have investigated the prevalence and impact of CR in patients undergoing extracranial carotid artery stenting, particularly transcarotid artery revascularization (TCAR).

Dual Antiplatelet Alternatives are Associated With Increased Stroke and Death After Transcarotid Revascularization.

Objective: To define the risks associated with the replacement of dual antiplatelets for alternate medication regimens.

Background: Patients undergoing transcarotid artery revascularization (TCAR) for atherosclerotic disease in the Vascular Quality Initiative database from September 2016 to June 2022 were included. In all, 29,802 TCAR procedures were captured between 2016 and 2022, consisting of 24,651 (82.

In-situ bypass is associated with superior infection-free survival compared with extra-anatomic bypass for the management of secondary aortic graft infections without enteric involvement.

Objective: The optimal revascularization modality following complete resection of aortic graft infection (AGI) without enteric involvement remains unclear. The purpose of this investigation is to determine the revascularization approach associated with the lowest morbidity and mortality using real-world data in patients undergoing complete excision of AGI.

Methods: A retrospective, multi-institutional study of AGI from 2002 to 2014 was performed using a standardized database.

Operative Traumatic Aortic Injuries at an Urban Pediatric Hospital.

Purpose: Limited data are available describing the long-term results of pediatric patients undergoing aortic repair secondary to trauma. Therefore, this descriptive investigation was completed to abrogate this deficit.

Methods: A retrospective review of an urban level 1 pediatric trauma database maintained at a high-volume dedicated children's hospital between 2008-2018 was completed to capture all cases of severe traumatic aortic injury and associated demographics, mechanisms, injury severity, treatment, and clinical outcomes.

Aggressive Surveillance Is Needed to Detect Endoleaks and Junctional Separation between Device Components after Zenith Fenestrated Aortic Reconstruction.

Background: Junctional separation and resulting type IIIa endoleak is a well-known problem after EVAR (endovascular aneurysm repair). This complication results in sac pressurization, enlargement, and eventual rupture. In this manuscript, we review the incidence of this late finding in our experience with the Cook Zenith fenestrated endoprosthesis (ZFEN, Bloomington, IN).
