近年来应用肝动脉栓塞术(transcatheter arterial embo1ization,TAE)治疗肝癌引起了人们的重视,现就最近几年来的有关资料作一综述。 TAE治疗的效果肿瘤坏死:70年代后,TAE已逐渐取代了肝动脉结扎术。栓塞术通过阻断肝动脉的血供可使肿瘤的血液供应减少90～95%,而正常肝实质的血供仅降低30～40%,故阻断血流可使肝癌发生缺血性坏死。栓塞术后数周至数月再作动脉造影可见原来栓塞的血管再通,系因造影剂被吸收所致。日本杉田等对140例肝癌采用抗癌剂并栓塞治疗,52.6%以上病例肿瘤缩小达50%以上。
In recent years, the use of transcatheter arterial embolization (TAE) to treat liver cancer has attracted people’s attention. Now we have reviewed the relevant data in recent years. Effects of TAE Therapy Tumor Necrosis: After the 1970s, TAE has gradually replaced hepatic artery ligation. Embolization can reduce the blood supply of the tumor by 90 to 95% by blocking the blood supply to the hepatic artery, whereas the blood supply to the normal liver parenchyma only decreases by 30 to 40%, so blocking the blood flow can cause an ischemic necrosis of the liver cancer. Embolization from several weeks to several months after embolization showed that the original embolization of the recanalization was due to absorption of contrast agent. Japan’s Sugita et al used anticancer agents and embolization for 140 patients with HCC, and tumors were reduced by more than 50% in more than 52.6% of patients.
