Delayed presentation of ilio-iliac arteriovenous fistula following laparoscopic cholecystectomy treated with percutaneous graft-covered stent placement.

Major vascular injuries during laparoscopic cholecystectomy are rare, usually readily apparent, and immediately treated. We report a case of delayed presentation of a retroperitoneal vascular injury. The patient presented with abdominal pain and increasing edema of the lower extremities 1 year after laparoscopic cholecystectomy and was found to have an ilio-iliac arteriovenous fistula. Endovascular treatment was accomplished using a graft-covered polytetrafluoroethylene stent. The patient remained free of symptoms at 1-year follow-up.
