Biliary obstruction necessitating choledochojejunostomy as a complication of endovascular coil erosion.

We report the case of a 55-year-old patient presenting with biliary obstruction caused by coil migration from a recently performed embolization of a post-traumatic gastroduodenal artery pseudoaneurysm. Based on imaging findings, biliary drain placement was initially performed and the subsequent endoscopy demonstrated coil erosion into the common bile duct and duodenum, resulting in choledochoduodenal fistula. Choledochojejunostomy was thereafter performed to bypass the area of injury.
