Resolution of hepatopulmonary syndrome after auxiliary partial orthotopic liver transplantation in Abernethy malformation. A case report.
Congenital absence of portal vein and extrahepatic portocaval shunt, also referred to as an Abernethy type 1, is a rare malformation of the mesenteric vasculature. A 9-year-old girl presented with dyspnea on exertion and orthodeoxia. A diagnosis of an Abernethy malformation type 1b and hepatopulmonary syndrome (HPS) was made, and she underwent auxiliary partial orthotopic liver transplantation (APOLT). Symptoms and signs of HPS resolved 2 months after the operation. HPS in Abernethy syndrome is a manifestation of normal portal blood flow bypassing the liver and can be ameliorated by redirecting blood flow to a segment of liver with normal portal anatomy. APOLT is a feasible and successful surgical procedure for patients with Abernethy malformation and HPS.
