Abstract: Objective To explore the value of vascular enhancement technology (VET) in the evaluation of therapeutic efficacy of stenting for Budd-Chiari syndrome (BCS).Methods Two-dimensional ultrasound,color Doppler and VET were performed on 39 BCS patients with 41 stents,the static and dynamic images of stents and vessels with stents were stored.VET and two-dimensional ultrasound imaging quality of intravascular stent were compared.Patients with stent stenosis found by ultrasound were examined by digital subtraction angiography(DSA).The ranges of stent thrombosis were measured by DSA and VET and the difference was compared.Results VET image quality scores of endovascular stent were higher than those of the two-dimensional ultrasound,the difference was statistically significant.The ranges of stent thrombosis measured by VET were similar to DSA.Conclusions VET can improve the clarity of intravascular stents.VET and color Doppler can enhance the clinical value of ultrasound in the evaluation of therapeutic efficacy of stenting for BCS.
