🌱 來自: Budd-Chiari syndrome

diagnostic test of Budd-Chiari syndrome

• ± ↑ AST, ALT & Aϕ; Doppler hepatic veins (85% Se & Sp); CT (I+) or MRI/MRV → vein occlusion or ↑ caudate lobe (separate venous drainage); hepatic venography gold standard w/ “spider- web” pattern + assess venous pressure; biopsy only if unclear

Elevated levels of AST, ALT, and Alpha-fetoprotein (Aϕ) may be present, but are not required for diagnosis.

Diagnostic Tests

• Doppler Ultrasound of hepatic veins: 85% sensitivity and spe
• Computed Tomography (CT) or Magnetic Resonance Imaging/Magnetic Resonance Venography (MRI/MRV)
• to assess for vein occlusion or increased size of caudate lobe (indicating separate venous drainage)
• Hepatic venography is considered the gold standard with a “spider-web” pattern seen in the veins and venous pressure assessed.

• Biopsy is only necessary if the diagnosis is unclear after the above tests.
