Brief summary

To validate the safety and efficacy of TIPS (Transjugular Intrahepatic Portosystemic Shunt) using PTFE covered stent in the treatment of portal hypertension.

Detailed description

This trial is a prospective multi-center single-arm confirmatory study. A total 177 subjects will be enrolled in multiple centers nationwide. Subjects who meet the trial requirements, fulfill the inclusion criteria, voluntarily participate in the study, and provide informed consent will undergo TIPS using the PTFE covered stent for the treatment of portal hypertension. Follow-up assessments will be conducted at discharge, as well as at 30 days, 90 days, 180 days and 360 days postoperatively. Secondary endpoint measures include surgical success rate, all-cause mortality, device/procedure-related mortality, incidence of adverce events, and serious adverse event rates. The trial aims to comprehensively assess the safety and efficacy of the PTFE covered stent produced by Enlight Medical Technologies (Shanghai) Co., Ltd..

Interventions

The experimental device is a class III implanted shunt device, which will be used to create a shunt between intrahepatic and portosystemic to reduce portal hypertension.

MeasureTime frameDescription
Primary shunt patency rate1 yearshunt dysfunction was defined as a TIPS stenosis \>=50% or complete occlusion. Primary patency referred to continuous unassisted patency of the shunt.

Secondary

MeasureTime frameDescription
Treatment success rateduring the perioperative periodTreatment success is defined as the success of the procedure without major adverse event.
Technical success rateimmediately after procedureSuccessful implantation of a PTFE covered stent to create an intrahepatic portosystemic shunt and successful retrieval of the delivery system.
Procedure success rateimmediately after procedurePPG (portosystemic pressure gradient) reduces more than 20% or PPG \<=12mmHg
