title: Control of solitary gastric fundal varices and portosystemic encephalopathy accompanying liver cirrhosis by balloon-occluded retrograde transvenous obliteration (B-RTO): a case report.
abstract: In a patient with liver cirrhosis complicated by solitary gastric fundal varices and portosystemic encephalopathy, Balloon-occluded retrograde transvenous obliteration (B-RTO) of the varices was performed. The gastric varices were decreased in size 2 weeks after treatment and had not recurred after 1 year. B-RTO successfully occluded the portosystemic shunt (gastrorenal shunt). Accordingly, the patient's blood ammonia levels, total bile acid level, and 15 min retention rate of indocyanine green decreased, and his hepatic encephalopathy improved. However, since consecutive increase in blood flow through the portal collateral vessels except for gastrorenal shunt vessel at 6 months and 1 year after B-RTO was noted, further careful follow-up may be required.
