Left Lobe Recurrent Hepatocellular Carcinoma Treated with Lipiodol-TAE via the Left Internal Mammary Artery

Abstract

A multinodular hepatocellular carcinoma (HCC) was treated with seven transarterial interventions via the hepatic artery over a 2-year, 5-month period before the eighth angiography showed a recurrent HCC in the anterior portion of the left hepatic lobe. The left internal mammary artery (IMA) was feeding the tumor. This was successfully treated with Lipiodol-transcatheter arterial embolization using a coaxial system via a branch of the left IMA. No complications resulted from the procedure. The left IMA should be considered as a possible feeding artery to an HCC occurring in the anterior portion of the left hepatic lobe.
