Hepatocellular Carcinoma in the Caudate Lobe of the Liver: Angiographic Analysis of Tumor-feeding Arteries According to Subsegmental Location

To investigate the tumor-feeding arteries in hepatocellular carcinoma (HCC) arising in the caudate lobe of the liver.From January 1998 to March 2004, 140 patients with 146 caudate HCCs underwent chemoembolization. Subsegmental location of the caudate HCC and the origin of the tumor-feeding arteries was determined with computed tomography and hepatic arteriography. On follow-up angiography at 6-96 months (mean, 24 months), changes in the...
