Extrahepatic arterial blood supply of hepatocellular carcinoma and interventional treatment / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the pattern extrahepatic arteriy supply to hepatocellular carcinoma and catheterization technique for interventional therapy.</p><p><b>METHODS</b>Routine celiac and superior mesenteric artery angiography was done before transcatheter arterial chemoembolization (TACE) for 78 collateral arterial pathways of 62 hepatocellular carcinoma patients. Super selective catheterization and transcatheter dual arterial chemoembolization (TDACE) to extrahepatic arterial and hepatic arteries were performed.</p><p><b>RESULTS</b>Extrahepatic blood supply was found in 43.1% of hepatocellular carcinoma patients. There was close correlation between extrahepatic arterial blood supply and location of tumor. Success rate of super selective extrahepatic artery catheterization was 71.8% by the combined use of RH, Cobra and SP catheters. Follow-up studies revealed reduction of tumor and complete dense deposition of lipiodol.</p><p><b>CONCLUSION</b>Ample extrahepatic arterial blood supply is found in hepatocellular carcinoma. Transcatherdual arterial chemoembolization is effective, necessary and feasible for hepatocellular carcinoma with extrahepatic arterial blood supply.</p>
