During Endovascular Aortic Repair in Difficult Iliac Artery Anatomy, Contralateral Snare Cannulation vs. Retrograde Gate Cannulation

Abstract

Endovascular Aortic Repair (EVAR) is a minimally invasive procedure employed to treat Abdominal Aortic Aneurysms (AAA). However, the presence of challenging iliac artery anatomy can complicate the procedure, making effective cannulation crucial. This paper compares two cannulation techniques: Contralateral Snare Cannulation (CSC) and Retrograde Gate Cannulation (RGC), in the context of EVAR performed on patients with difficult iliac artery anatomy. The study evaluates the technical success, procedural time, fluoroscopy time, and complication rates associated with each technique. Through a comprehensive review of clinical cases and literature, the findings suggest that while both techniques have distinct advantages and limitations, the choice of method should be tailored to the patient's specific anatomical challenges and the surgeon's expertise.
