Budd-Chiari syndrome: detection with color Doppler sonography

Area of Science:

• Medical Imaging
• Hepatology
• Vascular Ultrasound

Background:

• Budd-Chiari syndrome is a rare condition caused by obstruction of hepatic venous outflow.
• Accurate diagnosis and evaluation are crucial for effective management.

Purpose of the Study:

• To assess the diagnostic value of color Doppler sonography in newly diagnosed Budd-Chiari syndrome.
• To compare the efficacy of color Doppler sonography with conventional sonography.

Main Methods:

• Retrospective analysis of five patients with newly diagnosed Budd-Chiari syndrome.
• Evaluation of hepatic venous abnormalities and collateral formation using color Doppler sonography.
• Comparison with conventional sonography and other imaging modalities.

Main Results:

• Color Doppler sonography identified various hepatic venous abnormalities including narrowing, tortuosity, flow reversal, and absence.
• Collateral pathways such as hepatic venous to hepatic venous, hepatic venous to subcapsular systemic venous, and portosystemic were detected.
• Abnormal hepatic veins and collateral vessels were visualized more reliably than with conventional sonography.

Conclusions:

• Color Doppler sonography is a valuable tool for the initial diagnosis and comprehensive evaluation of Budd-Chiari syndrome.
• It enhances the detection of hepatic venous abnormalities and collateral circulation.
• This technique improves diagnostic confidence and identifies findings missed by conventional imaging.
