Abstract：
:Despite the availability of Doppler ultrasound, angiography still forms part of the protocol for evaluating children after orthotopic liver transplantation (OLT) at our department. To investigate whether Doppler ultrasound is a reliable method for evaluating the patency of the hepatic artery, portal vein, inferior vena cava, and the anastomotic site of the portal vein in children after OLT, we performed a prospective study in which Doppler ultrasound was compared with angiography in 38 children with 40 transplants (ten examinations on clinical demand and 49 examinations according to protocol). Good correlation was found in relation to demonstrating a patent hepatic artery (sensitivity 96% and specificity 100%). Two false-negative Doppler ultrasound results were attributable to technical difficulties and rejection. For evaluating the patency of the portal vein, Doppler ultrasound agreed with angiography in 58 of the 59 examinations (98%). The one and only false-positive angiography result was explained by inadequate opacification. Doppler ultrasound visualized stenosis of the portal vein three times more often than angiography. In seven children, Doppler ultrasound findings suspicious of pathology of the inferior vena cava were confirmed using cavography or surgery. Doppler ultrasound proved to be a reliable technique for evaluating the patency of the hepatic artery, inferior vena cava, and portal vein and the anastomotic site of the portal vein.
