Summary
Limb-shaking transient ischemic attack (LS-TIA) is a rare symptom of carotid artery occlusion. Successful surgical recanalization resolved LS-TIA in a patient, suggesting hemodynamic failure as a potential cause.
Area of Science:
- Vascular Neurology
- Cerebrovascular Disease
Background:
- Limb-shaking transient ischemic attack (LS-TIA) is an uncommon presentation of carotid artery occlusion.
- Common carotid artery occlusion (CCAO) is rare, with unclear natural history and treatment guidelines.
Observation:
- A 67-year-old female presented with transient unilateral limb shaking episodes.
- Imaging revealed right common carotid artery occlusion and corpus striatum hypoperfusion.
- The patient underwent retrograde common carotid endarterectomy for successful recanalization.
Findings:
- Surgical recanalization of the common carotid artery occlusion resolved the LS-TIA episodes.
- Corpus striatum hypoperfusion was identified as a potential mechanism for LS-TIA in CCAO.
Implications:
- This case highlights retrograde endarterectomy as a viable treatment for CCAO causing LS-TIA.
- Understanding hemodynamic failure mechanisms is crucial for managing LS-TIA secondary to carotid occlusion.

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
