Approximately one in six patients with portal hypertension who develop varices at sites of portosystemic venous collaterals has gastric varices due to hepatofugal flow into the gastric veins. Bleeding from gastric varices, though less common, has a higher mortality and morbidity compared to bleeding esophageal varices, which are easier to manage endoscopically. The efferent channel for gastric varices is mostly the gastrorenal shunt (GRS) which opens into the left renal vein. Balloon-occluded transvenous obliteration (BRTO) involves accessing the GRS with an aim to temporarily occlude its outflow using a balloon catheter and at the same time injecting sclerosant mixture within the varix so as to cause its thrombosis and thereby obliteration. BRTO is one of the mainstays of minimally invasive treatment for bleeding gastric varices. In the minority of cases where the GRS is absent, conventional BRTO is technically not possible. However, accessing the small alternate shunt from the inferior phrenic vein may be possible if one is aware of its existence.
