Using TIPS Stent Graft to treat complications of cirrhosis and portal hypertension

A Prospective, Multi-Center, Single-Arm Clinical Study to Evaluate the Effectiveness and Safety of LIVERTYTM TIPS Stent Graft in the Treatment of Cirrhosis and Complications of Portal Hypertension

This study is testing if a special stent can help people with liver cirrhosis and high blood pressure in the liver feel better and avoid serious complications over a year.

What this trial studies

This study evaluates the effectiveness and safety of the TIPS Stent Graft in patients suffering from portal hypertension due to liver cirrhosis. It is a prospective, multi-center, single-arm study that will follow participants for 12 months after treatment. The primary endpoint is to assess the stent patency at 6 months post-treatment. Eligible patients will be monitored for complications related to variceal bleeding and ascites.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with portal hypertension due to liver cirrhosis and a history of gastrointestinal bleeding or refractory ascites.

Not a fit: Patients who are pregnant, lactating, or have significant portal vein thrombosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of complications associated with cirrhosis and portal hypertension.

How similar studies have performed: Other studies have shown promising results with TIPS procedures, indicating a potential for success in this approach.
