Limb-shaking transient ischemic attack (LS-TIA) is a rare manifestation of carotid artery occlusion. Common carotid artery occlusion (CCAO) is a relatively rare condition, and both its natural history and recommendations for treatment are still unclear.
A 67-year-old female suffered from transient episodes of unilateral limb shaking. Computer tomographic angiography (CTA) showed long-segment occlusion of the right common carotid artery. Computer tomographic perfusion (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. The occlusion was successfully recanalized by retrograde common carotid endarterectomy, and the episodes of left limb shaking disappeared after surgery.

肢体抖动性短暂性脑缺血发作（LS-TIA）是颈动脉闭塞的一种罕见表现。颈总动脉闭塞（CCAO）是一种相对少见的病症，其自然病程及治疗建议仍不明确。
一名67岁女性出现单侧肢体抖动的短暂发作。计算机断层血管造影（CTA）显示右侧颈总动脉长段闭塞。计算机断层灌注成像（CTP）显示纹状体灌注不足，这提示血流动力学衰竭是颈总动脉闭塞继发LS-TIA的潜在机制。通过逆行颈总动脉内膜切除术成功使闭塞血管再通，术后左下肢抖动发作消失。
