Impact of Hypogastric Artery Coverage Versus Preservation on Clinical Outcomes of Endovascular Repair of Infrarenal Aortic Aneurysms

Abstract

During endovascular aneurysm repair (EVAR), iliac arteries are used as distal seal zones for stent grafts. Lack of adequate length in the common iliac artery necessitates landing in the external iliac artery and compromising pelvic blood flow through the internal iliac artery (IIA). Recently, the US Food and Drug Administration approved endografts as well as physician-modified endografts to preserve the blood flow of the IIA. However, evidence on the benefit of sparing pelvic blood flow is lacking.
