Dynamic CT scans reveal distinct patterns in Budd-Chiari syndrome, correlating liver morphology and enhancement with portal blood flow direction in acute and chronic stages.

Area of Science:

  • Radiology
  • Hepatology
  • Vascular Imaging

Background:

  • Budd-Chiari syndrome is a rare hepatic vascular disease characterized by obstruction of hepatic venous outflow.
  • Accurate diagnosis and staging are crucial for patient management and prognosis.

Purpose of the Study:

  • To evaluate the utility of dynamic CT scanning in characterizing Budd-Chiari syndrome.
  • To correlate CT findings with disease stage and portal blood flow dynamics.

Main Methods:

  • Retrospective multi-institutional study of 38 patients with Budd-Chiari syndrome.
  • Dynamic CT scanning was performed on all patients.
  • Angiography, inferior cavography, and wedge-hepatic venography were used for correlation.

Main Results:

Related Experiment Videos

  • Acute Budd-Chiari syndrome showed global liver enlargement and diffuse hypodensity on plain CT, with patchy enhancement post-contrast.
  • Chronic disease presented with liver morphology abnormalities and hypodensity in atrophic or peripheral areas.
  • Dynamic CT demonstrated patchy enhancement in most chronic cases, with correlations to portal blood flow direction.

Conclusions:

  • Dynamic CT provides valuable insights into the morphologic and hemodynamic changes in Budd-Chiari syndrome.
  • CT findings correlate with disease stage and can reflect alterations in portal blood flow.
  • This imaging modality aids in the comprehensive evaluation of Budd-Chiari syndrome.
