Abstract:
Objective To explore the value of the application of vascular enhancement technology (VET) in the diagnosis of Budd-Chiari syndrome (BCS) and the evaluation of the therapeutic efficacy of interventional therapy.Methods B-mode ultrasound,color Doppler and VET were performed on 93 patients with BCS for the systematic detection of intrahepatic vessels and the inferior vena cava (IVC),with the static and dynamic images of these vessels stored prior to interventional therapy.Subsequent to the operation,the same procedures were repeated on the vessels concerned and the images were recorded.The definitions of B-mode and VET images of the detected vessels were compared by two sonography experts.Regarding DSA as standard,the diagnostic accordance rate of VET and B-mode imaging of the diseased vessels was compared.Results Of the 613 vessels detected prior to intervention therapy,440 vessels images were distinct by B-mode and 533 by VET(P<0.05).VET demonstrated 37 intrahepatic collaterals which were invisible by B-mode.Regarding DSA as the gold standard,the diagnostic accordance rate of affected vessels of B-mode and VET was 69.2% and 92.5%,respectively(P<0.05).In total 103 therapeutic vessels,B-mode sonography and VET revealed 81 and 95 distinct vessels,respectively(P<0.05).Conclusions VET can improve the definition of veins and venous stents.The combination of VET and color Doppler can improve the clinical value of ultrasound in the diagnosis of BCS and evaluation of the therapeutic efficacy of interventional therapy.
