Endoscopic extraction of vascular embolization coils that have migrated into the biliary tract in a liver transplant recipient.
Hepatic artery pseudoaneurysm (HAA) is a rare vascular complication of liver transplantation. Minimally invasive radiological interventions are generally considered before seeking surgical treatment of HAA. Coil embolization of the aneurysmal sac and or exclusion of pseudoaneurysm by deploying a stent over the aneurysm are effective interventions to control hemobilia arising from the HAA. Migration of coils inside the bile duct is a rarely reported complication in post-hepatic transplantation. Treatment options remain largely unexplored due to the rarity of its occurrence. Endoscopic retrograde cholangiographic removal of migrated vascular coils in the common bile duct following embolization of HAA has not been described in a liver transplant setting. We report a liver transplant recipient who underwent uneventful and successful endoscopic removal of migrated coils into the bile duct.
