Iliac Pseudoaneurysm Stenting after Conventional Abdominal Aneurysm Repair

Abstract

Anastomotic iliac aneurysms after surgical repair of abdominal aortic aneurysms are associated with a significant morbidity and mortality. Conventional open surgical repair of such aneurysms involves general anæsthesia and may necessitate complex redo vascular reconstruction. We report a case of endoluminal treatment of a 35 mm aneurysm of the right common and external iliac arteries with a superadded external iliac artery stenosis in a 60-year-old female following surgical implantation of an aorto-biiliac prosthesis 25 years previously.After occlusion of the internal iliac artery with metal coils, the stenosis of the external iliac artery was treated by means of percutaneous transluminal angioplasty (PTA) via a transcutaneous right femoral artery approach. The aneurysm was then successfully excluded by the implantation of a stent-graft into the common and external iliac artery. Interventional stent graft placement under local anesthæsia provides a useful therapeutic approach for anastomotic aneurysms of the iliac arteries.
