Hepatic artery aneurysm involving the proper hepatic and gastroduodenal artery treated using a gastroepiploic artery in situ bypass.
We herein present the first known case of common hepatic artery aneurysm involving the proper hepatic artery treated with in situ bypass by using right gastroepiploic artery. A 55-year-old man was hospitalized after the incidental discovery of a low-echogenic mass with blood flow in the hepatic artery. Selective visceral arteriography demonstrated a hepatic artery aneurysm that filled via the superior mesenteric artery. The most proximal part of the common hepatic artery was occluded. A resection of aneurysm was performed, and the arterial blood flow was restored to the liver by mobilizing the right gastroepiploic artery and anastomosing the proper hepatic artery. This technique is preferable to grafting in that only one anastomosis is necessary and predicts that the results may be at least as good as with vein or prosthetic grafts.
