Bleeding gastric gastric varices (GVs) carry a higher morbidity and mortality than bleeding esophageal varices (EVs), which are easier to access and treat endoscopically using banding. Balloon-occluded retrograde transvenous obliteration (BRTO) of GVs is a minimally invasive treatment for such cases which relies on accessing the main efferent venous channel of these varices, i.e. the gastrorenal shunt (GRS) via the left renal vein . In cases lacking a GRS, alternate efferent channels such as the left inferior phrenic vein (IPV) can be accessed and BRTO of varices is possible. To our knowledge, only one such previous case has been reported in which the communication between the left IPV and left hepatic vein was utilised to perform a BRTO.
