RESUMEN
Budd-Chiari syndrome is an uncommon disorder, and it is caused by obstruction of the hepatic venous outflow or inferior vena cava above the hepatic vein. It may result from a large number of conditions, including primary congenital obstructions of the hepatic veins or inferior vena cava by webs or bands. Secondary causes include trauma, polycythemia vera, chronic leukemia, pregnancy, tumors and use of oral contraceptives. No definitive etiologic factors have been identified in two thirds of all cases (1-3). We recently experienced a case of Budd-Chiari syndrome caused by diaphragmatic hernia in 21-year-old man. Postoperative follow up CT showed normal venous flow after reintroduction of the liver into the abdominal cavity and closure of the diaphragm defect.

Vascular complications after liver transplantation may involve the hepatic artery, and hepatic and portal veins. Arterial complications are common and significant vascular complications include thrombosis or stenosis, as well as pseudoaneurysms. Venous complications include thrombisis or stenosis of the inferior vena cana, or hepatic or portal vein. Since recent evidence has shown that emergent revascularization leads to improved graft salvage and patient survival with a relatively low rate of late biliary complications, accurate and pronpt di-agnosis of hepatic arterial complications is important. Doppler US is a relatively inexpensive, accurate, and non-invasive method of diagnosing the vascular complications which may arise from liver transplantation.
