title: [Clinical value of contrast-enhanced ultrasound in the diagnosis of Budd-Chiari syndrome with inferior vena cava obstruction].
abstract: OBJECTIVE
  To explore the clinical value of contrast-enhanced ultrasound (CEUS) in the diagnosis of Budd-Chiari syndrome with inferior vena cava (IVC) obstruction.
  
  
  METHODS
  A total of 38 patients with Budd-Chiari syndrome with IVC obstruction were examined by CEUS before and after vascular interventional management, and the results were compared with angiographic findings.
  
  
  RESULTS
  The location and degree of IVC obstruction were clearly showed on CEUS. Enhancement was found in the occlusion site, and blood flow was narrowed at the stenosis site. The arrival time was earlier after treatment in the IVC obstruction, and it was positively correlated with the pressure of IVC( P< 0.05).
  
  
  CONCLUSIONS
  The location and type of the occlusion and stenosis in IVC can be accurately determined by CEUS. Therefore, CEUS can provide useful information for the selection of surgical procedures and post-operative effectiveness.
