肝癌的肝外动脉供血及其介入治疗

目的 探讨肝癌的肝外动脉供血规律、插管技术及介入治疗。方法 分析62例肝癌患者78条肝外动脉供血特征,对肝外动脉供血支行超选择插管,并同时进行肝动脉系统及肝外动脉供血支的双动脉化疗栓塞术。结果 肝外动脉供血占肝癌患者的43．1％,肝外动脉供血与肿瘤部位、大小密切相关;RH、Cobra、SP管配合使用,肝外动脉供血支插管成功率为71．8％。治疗后1个月复查,CT显示肿瘤缩小,碘油沉积致密完全。结论 肝癌有丰富的肝外动脉供血,对具有肝外动脉供血的肝癌患者采取双动脉内化疗栓塞是可行、必要和有效的。

Extrahepatic arterial blood supply of hepatocellular carcinoma and interventional treatment

Objective To study the pattern extrahepatic arteriy supply to hepatocellular carcinoma and catheterization technique for interventional therapy . Methods Routine celiac and superior mesenteric artery angiography was done before transc atheter arterial chemoembolization (TACE) for 78 collateral arter ial pathw ay s of 62 hepatocellular carcinoma patients. Super selective catheterizatio n and transcatheter dual arterial chemoembolization (TDACE) to extrahepatic arte rial and hepatic arteries were performed. Results Extrahepatic blood supply was found in 43.1% of hepatocellular carcinoma patient s. There was close correlation between extrahepati c arteri al blood supply and location of tumor. Success rate of super selective extra hepatic artery catheterization was 71.8% by the combined use of RH, Cobra a nd SP catheters. Follow up studies revealed reduction of tumor and comple te dense deposition of lipiodol. Conclusion 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 .
