肝癌由肝动脉和门静脉双重供血,肝癌细胞容易经门静脉肝内转移,故肝癌经肝动脉栓塞或手术切除后复发率高.选择性门静脉栓塞(SEPV)可扩大肝肿瘤手术切除的指征,有助于预防在肝癌切除术前和术中发生的癌细胞经门静脉肝内转移,与肝动脉栓塞联合应用治疗不能切除的肝癌和门静脉癌栓,可明显提高疗效.SEPV对肝功能有一定的损害,可使门静脉压升高,并有发生异位栓塞的可能.本文还介绍了SEPV的方法和栓塞物质及选择.
Liver cancer is supplied by the hepatic artery and portal vein, and liver cancer cells are easily transferred through the portal vein. Therefore, the recurrence rate of liver cancer after hepatic artery embolization or surgical resection is high. Selective portal vein embolization (SEPV) can expand the indications for liver tumor resection. Help prevent the intrahepatic metastasis of cancer cells before and during liver cancer resection, and hepatic artery embolization combined with the treatment of unresectable liver cancer and portal vein tumor thrombosis, can significantly improve the efficacy. SEPV has some damage to liver function , It can increase the portal pressure, and there may be ectopic embolization. This article also describes the SEPV method and embolic material and selection.
