title: Flow-preserved coil embolization using a side-holed indwelling catheter for common hepatic artery pseudoaneurysm: report of three cases.
abstract: We report three cases of hepatic artery pseudoaneurysm, which were all treated successfully using a combination of coil embolization and a side-holed 5F indwelling catheter for maintaining minimal hepatic artery blood flow with exclusion of the pseudoaneurysm. The tip of an infusion catheter was placed in the right hepatic artery and a side hole was positioned at the celiac axis. Coil embolization was then performed from the proper to the common hepatic artery using detachable coils. Hemostasis was achieved in all patients, with a final angiogram showing the hepatic arteries through the indwelling catheter. One major hepatic infarction and one focal liver abscess caused by reflux cholangitis manifested on postoperative days (PODs) 11 and 87, respectively. All patients survived and the indwelling catheter was removed on POD 136–382 without complication.
