Background:
Ipsilateral sensory motor symptoms associated with carotid artery stenosis are rare, and few reports are available in the literature.
Case Description:
We report the case of a 50-year-old man who presented with right hemiplegia that recurred 14 months later. A left hemisphere watershed infarction was detected. Repeated angiograms showed a left internal carotid occlusion and a right internal carotid stenosis that initially measured 50% and worsened to 80% after the second stroke.
Conclusions:
Repeated quantitative measurements of cerebrovascular reserve demonstrated the hemodynamic mechanism of the strokes and the role of a right internal carotid lesion in causing the recurrence of right hemiplegia.
