Successful repair of an arteriovesical fistula as a complication after coil embolization for right hypogastric artery aneurysm.

ABSTRACT

An 84-year-old man has a history of a right hypogastric artery aneurysm that was excluded with endograft several years ago. His course was complicated by a type II endoleak with an enlarging aneurysm that required multiple attempts of coil embolization. Several years later, he presented with gross hematuria and was found to have embolization coils extruding into his bladder and an arteriovesical fistula. As seen in this case, endovascular intervention for a type II endoleak is not benign. We describe a novel complication of an arteriovesical fistula that necessitated a difficult repair and ultimate revascularization.
