Evaluation of Variants in Hepatic Artery Anatomy on Conventional Angiography in Patients Undergoing Transarterial Chemoembolization (TACE): Experience at SIUT

Abstract

Objective: The purpose of this research is to evaluate common and uncommon variant of hepatic arterial anatomy that
usually come across during Hepatic Angiographies.
Study Design: Cross sectional study.
Methods: This study included 50 patients having history of Hepatocellular Carcinoma from May to October 2015. Hepatic Angiography (Transarterial chemoembolization for management of Hepatoma and identification of classical and variant anatomy of hepatic artery) was evaluated in angiography unit. All procedures were performed on Digital Subtraction Angiography (DSA) machine (Toshiba KXO100 G). Selective DSA of the superior mesenteric artery and celiac trunk is performed initially to evaluate the frequency of normal and variant arterial anatomy and secondly to determine origin and course of tumor-feeding vessels. Evaluation of common and uncommon variants of hepatic arteries was done by using Michel’s classification as reference standard.
