The case of a 67-year-old woman with symptoms related to the vertebro-basilar system and blood pressure difference of the upper extremities is presented. Colour-Doppler imaging (CDI) with additional spectral tracing revealed partial subclavian steal syndrome with retrograde flow in the left vertebral artery during systole, which could be significantly enhanced by reactive hyperemia after left arm exercise. Angiography confirmed a high-grade stenosis of the proximal subclavian artery and balloon angioplasty was performed. Noninvasive follow-up by CDI demonstrated regular antegrade vertebral artery flow at rest, but minimal retrograde systolic flow after left arm exercise.
本文报告了一例67岁女性患者，其出现与椎基底动脉系统相关的症状以及上肢血压差异。彩色多普勒成像（CDI）及附加频谱追踪显示存在部分锁骨下动脉盗血综合征，收缩期左椎动脉有逆流，左臂运动后反应性充血可使其明显增强。血管造影证实锁骨下动脉近端高度狭窄，并进行了球囊血管成形术。通过CDI进行的无创随访显示，静息时椎动脉血流正常，但左臂运动后收缩期逆流极小。
