Portosystemic encephalopathy in an 86-year-old patient : a clinical challenge.

Abernethy malformations are rare vascular abnormalities, classified into two types : type 1 if the portal vein is absent, type 2 when the portal blood is diverted into vena cava through a hypoplastic portal vein. These conditions present symptoms related to portosystemic shunting, and usually become clinically evident in children or young adults. Here we report the first case of Abernethy malformation diagnosed in an 86-year-old female patient affected by portosystemicencephalopaty. © Acta Gastro-Enterologica Belgica.
