Entirely Replaced Left Gastric Artery from the Left Hepatic Artery: A Case Report

Arteries originating from the celiac axis have numerous anatomical variations. When performing interventional and surgical procedures, it is important to be aware of these variations to have better outcomes and to prevent iatrogenic complications. We report on a case of a 62-year-old man who came to our institution to receive transarterial chemoembolization for hepatocellular carcinoma. The computed tomography and angiography revealed a rare anatomic variation: the entire left gastric artery originated from the left hepatic artery with no other accessory feature of the left gastric artery from celiac axis or aorta was seen. To our knowledge, this is the first report on the entirely replaced left gastric artery from the left hepatic artery that was confirmed by utilizing both computed tomographic and angiographic images.
