At present,in medical academic circle there is no consensus on the optimal diameter of the stent used in transjugular intrahepatic portosystemic shunt(TIPS).In 2021,the Advancing Liver Therapeutic Approaches Consortium(ALTAC)recommended the use of controllable diameter TIPS covered stent system in the performance of TIPS,the stent diameter of this system can be adjusted within the range of 8 mm to 10 mm,and its stability can be maintained for a long time.This system carries several advantages such as accurately regulating portal venous pressure gradient(PPG),optimizing hemodynamic target,protecting liver blood perfusion,reducing shunt-related complications,etc.,indicating that this system has a promising clinical application prospect.Through reviewing the relevant literature,this paper summarizes the research progress of controllable diameter TIPS covered stent system,aiming to better help clinicians engaged in related fields to gain a further understanding of this new technology.
