Pseudoaneurysm Formation at the Site of External Iliac Artery Stents: Percutaneous Stent-Graft Treatment

Abstract

Purpose: To present a patient who developed an asymptomatic large iliac pseudoaneurysm complicating stent-supported iliac artery recanalization. Case Report: The pseudoaneurysm was detected in an asymptomatic 69-year-old man during routine angiography 6 months after an uncomplicated procedure to implant 3 overlapping Palmaz stents in an occluded external iliac artery. There was no evidence of stent infection. During a second intervention, the pseudoaneurysm was successfully treated by percutaneous implantation of an EndoPro System I stent-graft. Contrast-enhanced spiral computed tomography at 6 and 12 months confirmed the durability of aneurysm exclusion and the patency of the endoprosthesis. Conclusions: Angioplasty-induced pseudoaneurysm is rare and usually asymptomatic, but elective percutaneous stent-graft repair should be considered as the first treatment option.
