虽然在超声引导下无造影剂的颈动脉介入治疗已有文献报道，但我们尚未发现有关椎动脉起始部支架植入治疗椎动脉狭窄的报道。在这里，我们报告了一例碘过敏患者，在没有造影剂的情况下，超声引导下支架置入术成功地治疗了椎动脉起始处的狭窄。在放置血栓保护装置的过程中、定位支架时以及评估支架开口时，对B型纵向图像进行监测。对于选定的患者，尤其是对造影剂过敏的患者，这项技术可能是一种替代选择。
Although ultrasonographically‐guided carotid interventions without contrast medium have been reported in the literature, we found no report regarding stenting of the vertebral artery origin for treatment of stenosis. Here, we report the case of an iodine‐allergic patient in whom a stenosis at the origin of the vertebral artery was successfully treated with ultrasonographically‐guided stent placement without contrast medium. B‐mode longitudinal images were monitored during the insertion of the embolism‐protection device, when positioning the stent, and for the evaluation of the stent opening. This technique can be an alternative option in selected patients, especially those allergic to the contrast medium.
