PURPOSE

Budd-Chiari syndrome (BCS) is a rare disease characterized by hepatic venous outflow tract obstruction. The study aimed to evaluate the diagnostic utility of ultrasound in confirming the diagnosis of BCS and to provide an overview of the clinical picture.

MATERIALS AND METHOD

In this retrospective single-center study, patients with an initial diagnosis of BCS were included. The files were analyzed concerning the ultrasound images and compared to computed tomography (CT) and magnetic resonance imaging (MRI). Main clinical signs of BCS were collected.

RESULTS

Data of 25 patients were analyzed. Doppler sonography showed the highest sensitivity (78.9%) with the highest specificity 97.4 (%) in confirming the correct diagnosis of BCS. Main imaging signs were obstruction in the hepatic veins (68.0%, 17/25 thrombotic), collaterals (91.7%, 11/12 intrahepatic), inhomogeneous liver parenchyma (7/21), and a hypertrophied lobus caudatus (18/21) (p < 0.01). All imaging signs could be detected with sonography. Hypertrophied lobus caudatus was seen exclusively in BCS. Furthermore, portal hypertension (9/25), liver cirrhosis (9/25), and ascites (19/25) can be diagnosed as non-specific signs of BCS (p < 0.01).The main clinical findings were elevated γ-GT levels in the laboratory (92.0%, 23/25, p < 0.01) and esophageal varices in endoscopy (12/25 p < 0.01). An association with myeloproliferative neoplasia (MPN) was frequently seen (10/25) (p < 0.01).

CONCLUSION

The present study demonstrates that sonography is an appropriate tool for the diagnosis of BCS and should be used as the first imaging procedure.
