Abstract
Acute variceal bleeding is a life-threatening condition that requires a multidisciplinary approach for effective therapy. The transjugular intrahepatic portosystemic shunt (TIPS) procedure is a minimally invasive image-guided intervention used for secondary prevention of bleeding and as salvage therapy in acute bleeding. Emergency TIPS should be considered early in patients with refractory variceal bleeding once medical treatment and endoscopic sclerotherapy fail, before the clinical condition worsens. Furthermore, admission to specialized centers is mandatory in such a setting and regional protocols are essential to be organized effectively. This procedure involves establishment of a direct pathway between the hepatic veins and the portal veins to decompress the portal venous hypertension that is the source of the patient's bleeding. The procedure is technically challenging, especially in critically ill patients, and has a mortality of 30%-50% in the emergency setting, but has an effectiveness greater than 90% in controlling bleeding from gastro-esophageal varices. This review focuses on the role of TIPS in the setting of variceal bleeding, with emphasis on current indications and techniques for TIPS creation, TIPS clinical outcomes, and the role of adjuvant embolization of varices.
