Coil embolization of an excluded internal iliac artery aneurysm with rapid expansion via gluteal artery approach.

The aim of the paper is to describe open approach of gluteal arteries for coil embolization of internal iliac artery (IIA) aneurysm. We observed enlargement of the IIA to 5.8 cm at the four-year follow-up evaluation of a 78-year-old man who had undergone surgical abdominal aortic aneurysm repair during which the IIA had been ligated at its origin. Following dissection of the gluteal artery with the patient in the prone position, a catheter was placed inside the aneurysmal sac, and coil embolization was possible to exclude the aneurysm. Postoperative angio-computed tomography showed good coil positioning and no demonstrable blood flow or type 2 endoleak.
