介入放射技术在治疗门静脉高压症食管静脉曲张出血和顽固性腹水中有着极其重要的作用。经颈内静脉肝内门体分流术(TIPS)用于治疗门静脉高压症已有20年历史,治疗数千例病人,技术成功率达90%,在全球广泛应用。TIPS虽存在肝性脑病和分流道阻塞的问题,近年来覆膜支架的应用显著提高分流道的通畅率。球囊阻塞的逆行胃底曲张静脉栓塞(B-RTO)是治疗胃底静脉曲张出血的另一种介入放射技术,在日本广泛应用,控制胃底静脉曲张出血成功率>90%。
Interventional radiotherapy plays an extremely important role in the treatment of esophageal variceal bleeding and refractory ascites due to portal hypertension. Transjugular intrahepatic portosystemic shunts (TIPS) have been used in the treatment of portal hypertension for more than 20 years. Thousands of patients have been treated with a technical success rate of 90% and are widely used in the world. TIPS Although there is hepatic encephalopathy and shunt obstruction problems, in recent years, the application of stent graft significantly improve the patency rate of the shunt. Balloon-occlusive retroversive gastric varices embolism (B-RTO) is another interventional radiotherapy for the treatment of gastric variceal bleeding, which is widely used in Japan to control the success rate of gastric variceal bleeding> 90%.
