Balloon-occluded retrograde transvenous obliteration of gastric varices

OBJECTIVE. The purpose of this review is to describe the clinical factors related to balloon-occluded retrograde transvenous obliteration, including the preparation needed, the technique and challenges, and the outcomes. CONCLUSION. Although the procedure can be performed when transjugular intrahepatic portosystemic shunt is contraindicated or when endoscopic management fails, balloonoccluded retrograde transvenous obliteration is successful as a first-line or second-line therapy. Gastric variceal rebleeding rates are low and serious complications are rare. Randomized controlled trials are required to evaluate the superiority of this procedure over other methods of treating gastric varices and to determine which sclerosant should be used. In the near future, this procedure may play a larger role in emergency care and in the management of non-gastric varices.
