Impact of Renal Chimney Grafts on Anatomical Suitability for Endovascular Repair in Ruptured Abdominal Aortic Aneurysm

Abstract

Roughly one third of patients with rAAA are anatomically suitable for EVAR; short aneurysm neck is the most common exclusion criteria. In appropriate cases, chimney grafts in one or both renal arteries may increase overall suitability by 12%. Suitability increases to ~ 60% when iliac access issues are additionally overcome.
