BACKGROUND AND AIMS: The diagnosis of Budd-Chiari syndrome (BCS) is essentially radiologic and is needed to plan appropriate therapy. We therefore conducted this proof of concept study to assess the utility of EUS in assessing the anatomy of BCS.
METHODS: This prospective, multicenter, observational study enrolled 50 consecutive patients with a diagnosis of BCS. All patients underwent a detailed EUS examination by 3 independent endosonographers, blinded to the anatomic details of BCS and others' findings. The EUS examination was compared between the endosonographers and with conventional angiography (where available) or magnetic resonance venography (MRV). Outcomes assessed were interobserver agreement, sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy in diagnosing pathologic lesions of BCS.
RESULTS: Fifty BCS patients (mean age, 34 years [range, 13-65]) underwent EUS. Results showed good agreement among endosonographers for diagnosing right hepatic vein (κ = .716) and left hepatic vein lesions (κ = .722), moderate agreement for middle hepatic vein lesions (κ = .660), and very good agreement for inferior vena cava (IVC) lesions (κ = .823). EUS demonstrated high sensitivity and positive predictive value, low interobserver variability, and overall diagnostic accuracy for BCS lesions.
CONCLUSIONS: EUS is a safe and accurate diagnostic tool for BCS. It can provide accurate mapping of hepatic veins, intrahepatic collaterals, and the IVC.
