Percutaneous Axillary Artery Access for Peripheral and Complex Endovascular Interventions: Clinical Outcomes and Cost Benefits.

Objectives: The aim of this study was to determine the safety, efficacy, and applicability of percutaneous axillary artery (pAxA) access in patients requiring upper extremity large sheath access during complex aortic, cardiac, and peripheral endovascular procedures. We also take this opportunity to address the potential cost-benefits offered by pAxA access compared to open upper extremity access.

Methods: A total of 26 consecutive patients, between June 2018 and October 2020, underwent endovascular intervention, requiring upper extremity access (UEA).

Application of the VORTEC Technique in Creating a Proximal Inflow Conduit in the Circumferentially-Calcified or "Lead-Pipe" Aorta.

A heavily calcified or "lead-pipe" aorta can present many challenges to any surgeon. There is higher risk of vessel wall rupture or disruption, distal embolization, and prolonged ischemia time of visceral organs due to longer clamp times. Hybrid revascularization techniques, which were originally described in visceral revascularization during complex aortic procedures, can be potentially utilized for lower extremity bypasses.

Accessory renal arteries involved in atherosclerotic occlusive disease at the aortic bifurcation.

Accessory renal arteries (ARAs) are embryonic remnants found in more than one-third of patients and occurring bilaterally in 10% of the population. Very few reports have documented such vessels arising near or at the level of the aortic bifurcation. Furthermore, the presence of ARAs has yet to be described in the context of atherosclerotic disease.

Pseudoaneurysm of Patent Ductus Arteriosus Following Previous PDA Closure: Case Report and Literature Review.

Background: Pseudoaneurysm developing after repair of a patent ductus arteriosus (PDA) is uncommon, with only a handful of cases reported in the literature. While older literature cites infection, recent series suggest that formation of pseudoaneurysm off of a ligated PDA attributed to breakdown in the suture line. Thoracic endovascular aortic repair (TEVAR) for this rare pathology has been demonstrated in selected case reports.
