Abstract

Introduction:
Hepatocellular carcinoma (HCC) accounts for 85–90% of primary liver cancers. Globally, it is the fifth most common cancer in men and the seventh in women.
Radiofrequency ablation (RFA), liver resection, and liver transplantation are the only curative options for patients with early-stage hepatocellular carcinoma (HCC). For those with intermediate-stage HCC (BCLC group B) who are not candidates for resection or ablation, trans-arterial chemoembolization (TACE) serves as the standard palliative treatment. In recent years, TACE has also emerged as a feasible treatment for certain advanced-stage HCC patients (BCLC group C).
To successfully perform trans-arterial chemoembolization (TACE), interventional radiologists must accurately map the feeding arteries of hepatocellular carcinoma (HCC), including hepatic artery variations and accessory or parasitic peri-hepatic arteries. Without proper mapping, the procedure can be technically difficult and incomplete. Extrahepatic collateral arteries supplying HCC are present in 17% to 27% of cases. Multidetector computed tomography angiography (MDCTA), a noninvasive technique, is used to visualize hepatic and perihepatic vessels and identify tumor-feeding arteries before TACE.
