Abernethy syndrome a rare cause of dyspnea a case report

Abstract

Abernethy malformations are rare vascular abnormalities of the splanchnic venous system. It´s about a congenital portosystemic shunts which result from the persistence of embryonic vessels. We report a case of type II Abernethy malformation which associates a hyperplasic intrahepatic portal vein, a deviation of blood to the inferior vena cava with side-by-side extrahepatic communication, in addition we noted an abnormal return of the pulmonary veins, and ectopic drainage of the superior vena cava into the right atrium. With uncommon dyspnea, congenital extrahepatic shunts are more and more diagnosed due to improved imaging techniques, but most are discovered by chance.
