Case reportEndovascular treatment for pseudoaneurysms arising from the hepatic artery after liver transplantation

SummaryHepatic artery pseudoaneurysm after liver transplantation is an uncommon but potentially lethal complication. Early diagnosis and treatment are essential to avoid life-threatening hemorrhage in these patients. We herein report the case of three patients who developed hepatic artery pseudoaneurysms after living donor liver transplantation. Two patients presented with massive duodenal bleeding secondary to erosion of the hepatic artery into the bile duct, and one patient presented with intra-abdominal bleeding. These patients were managed by catheter-based minimal invasive endovascular procedures including coil embolization and stent grafting. All the patients were treated successfully with uneventful recovery. This technique can be considered as an effective treatment option for hepatic artery pseudoaneurysms instead of a difficult surgical intervention.
