A comprehensive review of transvenous obliteration techniques in the management of gastric varices.

Bleeding gastric varices (GVs) is a life-threatening complication of portal hypertension, with higher morbidity and mortality rates compared with bleeding esophageal varices (EVs). The endovascular techniques for the management of GVs are mainly transjugular intrahepatic portosystemic shunt (TIPS) and transvenous obliteration of the GVs. Transvenous obliteration techniques can be an alternative or an adjunct to TIPS for treatment of GVs, depending on the clinical scenario, and are less invasive than TIPS. However, these procedures are associated with increased portal pressure and related complications, mainly worsening of the EVs. In this article, the different techniques of transvenous obliteration of GVs, their indications, contraindications, and outcomes are discussed.
