近年来国外普及了选择性动脉内导管插管法。利用此法可以封闭动、静脉瘘和阻塞肿瘤侵及的动脉。另外还发展了经皮经肝门脉导管插入技术,因此可使导管插到门脉各段以及其分枝,从而可得更明确的显像。在上述技术基础上,1974年Lunderguist和Vang报告了利用经皮经肝门脉导管法(Pe- In recent years, selective arterial catheterization has been popularized abroad. This method can be used to block arterial and venous spasm and block the arteries that the tumor invades. In addition, percutaneous transhepatic portal vein catheterization has also been developed. This allows the catheter to be inserted into each segment of the portal vein and its branches, resulting in more definitive visualization. Based on the above techniques, in 1974 Lunderguist and Vang reported the use of percutaneous transhepatic portal vein catheterization (Pe-
