经颈静脉肝内门体分流双支架技术研究进展

经颈静脉肝内门体分流术(TIPS)目前已成为治疗肝硬化门静脉高压及其并发症的主要方法.TIPS专用Viatorr支架2015年底在中国上市,但至今未能在国内广泛应用,国内多个中心目前仍采用裸支架与覆膜支架各1枚叠加释放的双支架技术模拟Viatorr支架行TIPS.双支架技术具有独特优势,但在远期疗效上不及单支架植入.该文就TIPS双支架技术分类与优势、术后分流道功能障碍原因、术后随访、分流道功能障碍处理处理等研究进展作一综述,以期更好地发挥该技术在肝硬化门静脉高压治疗中的作用.

Dual stent technology used for TIPS: recent progress in research

Nowadays,transjugular intrahepatic portosystemic shunt (TIPS) has already become the main means for the treatment of portal hypertension and its complications due to cirrhosis.The Viatorr stent that is specifically designed for TIPS has been available in China since the end of 2015,but it has not been widely used in clinical practice in China so far.At present,superimposed release dual-stent technology by using one bare stent and one covered stent,as simulation of Viatorr stent,to perform TIPS is still employed in many clinical centers in China.Dual stent technology carries unique advantages,although the long-term efficacy of dual-stent implantation technology is not as good as that of single-stent implantation technology.This paper aims to make a comprehensive review about the dual-stent technology used for TIPS,focusing on the dual-stent technique classification and advantages,the causes and the managements of postoperative shunt dysfunction,etc.so as to let this technique can be mnore effectively used in treating portal hypertension caused by cirrhosis.
