摘要
目的探讨锁骨下动脉窃血综合征的彩色多普勒超声特征和诊断价值。方法回顾性分析21例锁骨下动脉窃血综合征患者的超声影像学资料,并与DSA或MRA结果对照分析。结果锁骨下窃血综合征发生于左侧病变16例,右侧5例;其中隐性窃血(O级)2例,早期短暂性窃血(1级)3例,晚期短暂性窃血(2级)6例,完全窃血(3级)10例。患侧椎动脉反流程度与该侧锁骨下动脉或无名动脉狭窄程度呈正相关。结论椎动脉反流是锁骨下动脉窃血综合征的重要特征。根据椎动脉的不同反流程度可以推测锁骨下动脉或无名动脉的狭窄程度。
Objective To study the ultrasonic features and diagnostic value of ultrasonography in subclavian steal syndrome （SSS）. Methods Ultrasound images of 21 patients with SSS were analyzed and compared with the results of CT or MRA. Results Of the 21 patients with SSS,sixteen were on left side and five on right side,including latent stage in two cases,early transient stage in three cases, late transient stage in six cases, complete retrograde flow stage in ten cases. The retrograde flow in the vertebral artery correlated with the degree of stenosis of ipsilateral proximal subclavian or innominate artery. Conclusion The degree of retrograde flow in vertebral artery has positive relation with the degree of stenosis in proximal subclavian or innominate artery in SSS.
