An 80-year-old woman with hepatic encephalopathy and esophagogastric varices was admitted. Doppler sonography and arteriography demonstrated an arterioportal fistula in the right anterior superior segment of the liver. Two attempts at transcatheter arterial embolization failed to manage the fistula and portacaval collaterals. We carried out hepatectomy and balloon-occluded retrograde transvenous obliteration, by which the portal flow changed from hepatofugal to hepatopetal. The resected specimen demonstrated multiple small holes in the right portal vein, which are arterioportal fistula. The underlying liver was normal. After treatment, esophagogastric varices and hepatic encephalopathy were markedly improved. Hepatectomy is useful as a reliable therapy for arterioportal fistula in case of failure of transarterial embolization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
