摘　　要：目的评价超声在锁骨下动脉(SCA)及椎动脉(VA)狭窄血管内支架成形术中的应用价值。方法应用超声观察32例患者SCA、VA支架术后狭窄血管处支架位置、支架内及远端的收缩期峰值流速(PSV)、支架内有无血栓及再狭窄等情况,判断其疗效。结果支架置入术后超声示狭窄处血管内径较术前明显增宽,PSV、RI减低,100%狭窄改善,无一例≥50%的再狭窄发生。结论超声是评价SCA、VA狭窄支架成形术后疗效的首选检查方法。Objective To evaluate the role.of color Doppler ultrasonography in endovascular therapy of vertebral or subclavian arterial stenosis with stents. Methods Thirty-two patients with vertebral or subclavian arterial stenosis were investigated by color Doppler ultrasound after stent treatment. The location of stents, peak systolic velocity （PSV） inside and at distant place of stents were measured. Thrombosis or restenoses were noted. Results The results of stent treatment of symptomatic atherosclerotic stenosis in original segment of vertebral or subcalvian artery were satisfied. The diametter of stenostic artery increased. The PSV, RI decreased. There were not any cases of restenosis ≥50% after the procedure. Conclusion Color Doppler ultrasonography is the method of first choice in assessing the therapeutic effect of vertebral or subclavian artery with stents and follow-up in the long term.
