What are the benefits of having carotid endarterectomy after stoke if carotid artery stenosis is the cause?

Dr. Ali Sheikh, in terms of patients who have had a stroke and the cause is a carotid artery stenosis, a high-grade carotid artery stenosis, a tight narrowing in the artery to the brain, what's the advantage of having a carotid endarterectomy? What's the trial data? The NESC trial was the largest trial done to look for the efficacy of carotid surgery in these cases, which run over a two-year period. It showed that if carotid endarterectomy is done within a time frame of two weeks. It reduces the risk of the recurrence of a stroke by 17% and a disabling stroke by 10%. Thank you.
