title: A case of an unruptured hepatic aneurysm on the common hepatic artery at the junction of the gastroduodenal and proper hepatic arteries treated with transcatheter arterial embolization.
abstract: Hepatic aneurysms are rare, but can prove fatal once they rupture. Transcatheter arterial embolization (TAE) is performed as a prophylactic treatment. The position of the aneurysm determines the degree of difficulty of TAE. Maintaining blood flow to the liver can become difficult, particularly when the aneurysm is at an arterial junction. The patient was a 72-year-old man diagnosed with a hepatic aneurysm. The aneurysm was situated on the common hepatic artery at the junction of the gastroduodenal and proper hepatic arteries. TAE was performed with framing, followed by coil embolization. Blood flow to the liver was maintained via the gastroduodenal artery. Appropriate framing is important for safe and efficient TAE.
