Clinical Study of PTFE Covered Stent for Treating Portal Hypertension
- Conditions
- Portal Hypertension
- Interventions
- Device: Transjugular Intrahepatic Portosystemic shunt
- Registration Number
- NCT06117735
- Lead Sponsor
- Enlight Medical Technologies (Shanghai) Co., Ltd
- 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..

Group Intervention Description PTFE covered stent Transjugular Intrahepatic Portosystemic shunt Use the experimental device, PTFE covered stent to treat protal hypertension.
- Primary Outcome Measures
Name Time Method Primary shunt patency rate 1 year shunt dysfunction was defined as a TIPS stenosis \>=50% or complete occlusion. Primary patency referred to continuous unassisted patency of the shunt.
- Secondary Outcome Measures
Name Time Method Technical success rate immediately after procedure Successful implantation of a PTFE covered stent to create an intrahepatic portosystemic shunt and successful retrieval of the delivery system.
Procedure success rate immediately after procedure PPG (portosystemic pressure gradient) reduces more than 20% or PPG \<=12mmHg
Treatment success rate during the perioperative period Treatment success is defined as the success of the procedure without major adverse event.
