Suprarenal stent perforation after endovascular abdominal aortic aneurysm repair

Abstract

A 66-year-old man with an abdominal aortic aneurysm previously repaired with an endovascular stent graft presented to our facility with worsening midabdominal and back pain. Previous postoperative surveillance computed tomography scans were unremarkable, showing excellent stent-wall apposition and a shrinking aneurysm sac; however, imaging done on his arrival identified a contained rupture at the level of the celiac artery containing a perforating suprarenal stent. We repaired this rupture with a surgeon-modified fenestrated stent graft. To our knowledge, this is the first reported case of penetration of the native aorta by a suprarenal stent in the absence of infection or trauma.
