Balloon-occluded retrograde transvenous obliteration of gastric varix draining to the IVC via the circurnaortic renal vein

The authors encountered a patient with gastric varices draining to the IVC not only via the usual route of the left renal vein but also via a circumaortic renal vein. Balloon-occluded retrograde transvenous obliteration (B-RTO) of the gastric varix was performed with balloon occlusion of the circumaortic renal vein and retrograde injection of sclerosing agent (5% of ethanolamine oleate) into the varix. Eradication of the gastric varix was confirmed on endoscopic examination 2 months later. We document the first case of B-RTO performed for gastric varix via the circumaortic renal vein. Details of this rare occurrence and implications for treatment are presented herein. (c) 2005 Elsevier B.V. All rights reserved.
