    Real-time ultrasonography (US) is effective for diagnosing acute Budd-Chiari syndrome by visualizing hepatic vein abnormalities. However, cavography remains essential for comprehensive evaluation due to potential US limitations.

    Area of Science:

    • Radiology and Medical Imaging
    • Hepatology
    • Vascular Medicine

    Background:

    • Budd-Chiari syndrome involves hepatic venous outflow obstruction.
    • Accurate diagnosis is crucial for timely intervention and improved patient outcomes.
    • Conventional imaging methods have limitations in visualizing hepatic veins.

    Purpose of the Study:

    • To evaluate the utility of real-time ultrasonography (US) in diagnosing Budd-Chiari syndrome.
    • To compare US findings in acute versus chronic Budd-Chiari syndrome.
    • To identify the role of US in relation to other diagnostic modalities like cavography.

    Main Methods:

    • Real-time ultrasonography (US) was performed on twelve patients with proved Budd-Chiari syndrome (eight acute, four chronic).
    • Specific US findings indicative of hepatic vein abnormalities were documented.

  • Liver morphology and caudate lobe changes were assessed.

    • Main Results:

    • In acute cases, US detected abnormalities in at least one hepatic vein (stenosis, dilatation, thrombosis, etc.).
    • Hepatic veins were often not visible in chronic cases.
    • Liver morphology changes were noted in most patients, except those with recent onset; caudate lobe hypertrophy was less common.

    Conclusions:

    • Real-time ultrasonography (US) is the primary imaging modality for the initial diagnosis of acute Budd-Chiari syndrome.
    • US can identify characteristic hepatic vein changes, but may miss some caval thromboses or hepatic vein webs.
    • Cavography should be routinely performed, while hepatic phlebography is reserved for specific indications.
