RECURRENT RIGHT HEMIPLEGIA ASSOCIATED WITH PROGRESSIVE IPSILATERAL CAROTID-ARTERY STENOSIS

Background Ipsilateral sensory motor symptoms associated with carotid artery stenosis are rare, and few reports are available in the literat ure. Case Description We report the case of a 50-year-old man who pres ented with right hemiplegia that recurred 14 months later. A left hemi sphere 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 stro ke. 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 r ight hemiplegia.
