Abstract 16209: Safety and Efficacy of Percutaneous Groin Access Closure vs. Surgical Cutdown for Thoracic Endovascular Aortic Repair and Transcatheter Aortic Valve Replacement: A Single-Center Retrospective Analysis

IntroductionThoracic endovascular aortic repair (TEVAR) and transcatheter aortic valve replacement (TAVR) necessitate large-bore arterial access for stent/valve delivery. With improvement of device delivery technology, percutaneous access has become the standard. This may be associated with fewer complications, though literature is conflicting. The purpose of this study was to compare outcomes of open vs. percutaneous large bore arterial access at a single institution.HypothesisPercutaneous arterial access for device delivery is associated with fewer complications than surgical cutdown.MethodsIncluded were 746 patients who underwent TEVAR or TAVR between over 13 years. Only groins accessed for delivery sheath were included for analysis, with size ranging from 12-28 French (Fr.). Complications assessed included bleeding (hematoma, perforation, rupture, pseudoaneurysm), infection, seroma, dissection, and embolization.ResultsPatient characteristics are summarized in Table 1. Sheath diameter was predictive of conversion to open with a median of 20Fr. (IQR 16-22) vs. 16 Fr. (IQR 14-20) in cases that were completed percutaneously (p
