Long-segment common carotid occlusion presenting with limb-shaking transient ischemic attack: a case report
View through CrossRef
Abstract
Background: Limb-shaking transient ischemic attack (LS-TIA) is a rare manifestation of carotid artery occlusion.
Case presentation: A 67-year-old female suffered from transient episodes of unilateral limb shaking. CTA showed long-segment occlusion of the right common carotid artery. CTP demonstrated hypoperfusion of the corpus striatum, which suggests that hemodynamic failure is a potential mechanism underlying the LS-TIA secondary to common carotid artery occlusion.
Conclusion: The occlusion was successfully recanalized by retrograde common carotid endarterectomy, and the episodes of left limb shaking disappeared after surgery. Hypoperfusion of the corpus striatum might be a potential mechanism underlying the LS-TIA secondary to common carotid occlusion.
Keywords: Limb-shaking, TIA, common carotid occlusion, visual impairment, corpus striatum.
