Type IA endoleak caused by interlocked suprarenal bare-metal stents after endovascular abdominal aortic aneurysm repair with successful endovascular rescue

Abstract

A physically active 90-year-old man underwent endovascular repair of an asymptomatic but enlarging abdominal aortic aneurysm. Postoperative computed tomography demonstrated entanglement of nonadjacent proximal bare-metal stents. This was associated with graft infolding and a type IA endoleak. The patient underwent percutaneous transluminal angioplasty and placement of a Palmaz stent. Subsequent surveillance imaging showed resolution of the type I endoleak >1 year later. This report demonstrates an uncommon cause of stent graft infolding, an already rare complication of endovascular aneurysm repair, and highlights the need to carefully assess the morphologic appearance of the proximal fixation stents after graft deployment.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
