TIPS: an update

Area of Science:

• Interventional Radiology
• Hepatology
• Gastroenterology

Background:

• Portal hypertension is a significant complication of cirrhosis.
• Variceal bleeding and refractory ascites are major challenges in managing portal hypertension.
• Transjugular intrahepatic portosystemic shunt (TIPS) has evolved as a key intervention.

Purpose of the Study:

• To review the efficacy and indications of TIPS in managing portal hypertension.
• To highlight the impact of covered stents on TIPS patency rates.
• To discuss the role of TIPS as a rescue treatment for acute variceal bleeding and refractory ascites.

Main Methods:

• Review of current literature on TIPS procedures and outcomes.
• Analysis of data regarding shunt insufficiency and the role of covered stents.
• Evaluation of TIPS as a second-line treatment for variceal re-bleeding and as a primary treatment for refractory ascites.

Main Results:

• Covered stents significantly improve TIPS patency, reaching up to 90%.
• TIPS is a highly effective, minimally invasive rescue treatment for acute variceal bleeding, crucial before multi-organ failure.
• TIPS is indicated for 10-20% of patients experiencing recurrent bleeding despite first-line therapy.
• Five randomized studies suggest comparable survival for TIPS versus paracentesis in refractory ascites, though recommendations remain debated.

Conclusions:

• TIPS, especially with covered stents, is a safe and effective treatment for portal hypertension, variceal bleeding, and refractory ascites.
• Optimal timing of rescue TIPS is critical for achieving hemostasis and preventing complications in cirrhotic patients.
• While TIPS shows promise for refractory ascites, further consensus is needed for definitive recommendations.
