Selective Segmental Portal embolization Following Transcatheter Arterial Embolization for Hepatocellular Carcinoma

Abstract

Thirty one patients with hepatocellular carcinoma (HCC) had selective segmental portal embolization (SSPE) combined with transcatheter arterial embolization (TAE) for improved results of the tumor necrosis and minimization of liver disfunction after surgery. Lipiodol + Ethanol was used as the embolic material. After SSPE, liver functional damage was not severe. Portal vein pressure was significantly elevated just after SSPE. Hepatectomy was performed in 7 with liver cirrhosis of these 31 patients. In comparison with 12 patients who underwent TAE alone, liver functional damage was slight, and the mean necrotic ratio of the tumor was significantly higher.
