65 female with history of stroke has severe narrowing on right carotid has passed out and fallen eye sight blurry should stents be done?

Carotid narrowing: If stroke affected right brain and carotid narrowed over 50% then endarterectomy (CEA) is option. CEA has lower stroke rate than stent but higher risk of other problems. One option for you is to go to a provider that does both CEA and carotid stents. Decreased vision and falling often not related to carotid stenosis so thorough cardiac & neuro evaluation necessary before intervention.
