Dual stent technology used for TIPS: recent progress in research / 介入放射学杂志

ABSTRACT

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.
