摘要
目的探讨超声血管增强技术（VET）在布一加综合征（BCS）支架置人术后疗效评估中的应用价值。方法对39例BCS置入支架患者共41个支架进行二维超声、彩色多普勒及VET检查，存储支架及所在血管的静态及动态图像，比较血管内支架的二维与VET图像质量。对超声检查发现的支架狭窄的患者行数字减影血管造影（DSA）检查，测量支架内血栓范围，并与VET检查结果进行比较。结果VET技术显示血管内支架图像质量评分高于二维超声，二者比较差异有统计学意义。VET显示的支架内血栓范围与DSA结果相近。结论VET可改善血管内支架的清晰度，与彩色多普勒相结合，提高了超声在BCS支架置人术后疗效评估中的应用价值。
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.
