[Congenital absence of the portal vein (CAPV). Two cases of Abernethy malformation type 1 and review of the literature].
The Abernethy malformation is a rare congenital portosystemic shunt in which the blood directly drains into the systemic vein bypassing the liver either through a complete (type 1) or a partial shunt (type 2). The diagnosis is most frequently established primarily with ultrasound. CT and MRI are used for further classification of the shunt and assessment of accompanying liver tumors and malformations. There is a wide spectrum of therapeutic options ranging from noninvasive conservative treatment to liver transplantation. The main prognostic factors are the occurrence of concomitant hepatic neoplasms and hepatic encephalopathy. We report two cases diagnosed with a type 1 shunt, hepatic encephalopathy, and associated liver tumors who underwent successful liver transplantation after having considered all therapeutic options.
