用止血海绵作为栓塞物的肝动脉栓塞术,已成为肝细胞癌的普通疗法。但有两个问题,第一,因损伤肝动脉,限制了操作次数,加上侧支循环发达,栓塞困难。第二,重度的肝功障碍或大的门脉内肿瘤栓子不能做栓塞术。为解决这些问题,作者用病人自身凝血块作栓塞物(血栓),进行了新的尝试。肝动脉栓塞术的栓塞物从作用时间分为短、中、长三种。自身凝血块是作用时间短的栓子。作者为了区别与普通的TAE(经导管动脉栓塞)把此法称作为S-TAE(经导管短时间动脉栓塞)。S-TAE有以下方法。 A法:用血栓在肝动脉枪塞一定时间后,动脉注
Hepatic artery embolization using a hemostatic sponge as an embolus has become a common treatment for hepatocellular carcinoma. However, there are two problems. First, because of the damage to the hepatic artery, the number of operations is limited, and the collateral circulation is developed, making embolization difficult. Second, severe liver dysfunction or large portal vein tumor emboli cannot be used for embolization. In order to solve these problems, the authors used a patient’s own clot as an embolus (thrombus) and made new attempts. The embolization of hepatic artery embolization can be divided into three types: short, medium, and long. Self-clotting clots are embolus with short duration of action. The authors referred to this method as S-TAE (transcatheter short-term arterial embolization) in order to distinguish it from common TAE (transcatheter arterial embolization). S-TAE has the following methods. A method: After a certain time with thrombus in the hepatic artery, arterial injection
