Abstract

Coil migration is an extremely rare but hazardous complication of aneurysmal coil embolization. Only 1 case report has described coil migration following endovascular exclusion to gastrointestinal (GI) tract. We report the experience of a case of colon penetration caused by embolization coil placed for internal iliac aneurysm. A 66-year-old man visited the Emergency Department for hematochezia that had persisted for 3 months. Stent insertion and coil embolization of left internal iliac artery aneurysm had been performed on the patient 18 months ago. Colonoscopy was performed. It suggested penetration of sigmoid colon by embolization coil and diverticulum. Angiography revealed extravasation of contrast media at left internal iliac artery. Covered stent deployment was done in the left internal iliac artery. One week after the stent insertion, the patient underwent anterior resection, aneurysm resection, and coil removal. The patient recovered without complications. He was discharged at 2 weeks after the operation.
