Pseudoaneurysm formation at the site of external iliac artery stents: Percutaneous stent-graft treatment

Purpose: To present a patient who developed an asymptornatic large iliac ps eudoaneurysm complicating stent-supported iliac artery recanalization. Case Report: The pseudoaneurysm was detected in an asymptornatic 69-year-ol d 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, t he pseudoaneurysm was successfully treated by percutaneous implantation of an EndoPro System I stent-graft. Contrast-enhanced spiral computed tomograp hy at 6 and 12 months confirmed the durability of aneurysm exclusion and th e patency of the endoprosthesis. Conclusions: Angioplasty-induced pseudoaneurysm is rare and usually asympto matic, but elective percutaneous stent-graft repair should be considered as the first treatment option.
