Abstract This retrospective study was designed to evaluate duplex sonography in the diagnosis and follow-up of patients with Budd-Chiari syndrome. Thirteen patients with clotting disease and histologically proven Budd-Chiari syndrome (3 acute and 10 chronic cases) were examined, using conventional duplex sonography (n=5) or colour-coded duplex sonography (n=8). Results were compared with CT in 6 cases, MRI in 11, coeliac and mesentric angiography in 5, and hepatic wedge venography and cavography in 6. Of 39 hepatic veins examined, 33 had an abnormal appearance on ultrasound studies: endoluminal thrombus, stenosis, dilatation, thick wall echoes. Doppler findings included total obstruction of 8 hepatic veins, reversed flow in 22 hepatic veins and intrahepatic collaterals with continous non-phasic flow in all cases. Duplex sonography showed portal thrombosis (n=1), evidence of portal hypertension (n=8) and inferior vena cava thrombosis (n=2). Nine patients were treated surgically. Patency of portocaval shunts was correctly assessed with colour coded duplex sonography in 8 of 9 patients. We believe that colour Doppler imaging is the procedure of choice for initial diagnosis of Budd-Chiari syndrome.
