Which is true about carotid stenosis:
Correct Answer: Aspirin reduces risk of TIA
Description: Answer is D (Aspirin reduces risk of TIA): Antiplatelet therapy (including Aspirin) is recommended for medical therapy in patients with asymptomatic carotid stenosis to reduce the risk of TIA's. Carotid aery stenosis is not common in the External Carotid Aery Carotid Aery stenosis is common at the bifurcation of the common carotid aery and internal carotid aery. -Harrison Embolism in the Middle Cerebral Aery does not lead to ipsilateral hemiplegia Embolic material can dislodge from a plaque at the bifurcation of the common carotid aery and occlude a more distal middle cerebral aery. However such occlusion will lead to contralateral hemiplegia and not ipsilateral hemiplegia. Bruit does not always indicate the severity of lesion Bruit may he associated with tight stenotic lesions, but as the stenosis grows tighter and flow distal to the stenosis gets reduced, the bruit becomes fainter and may disappear when complete occlusion is imminent.
