Patients with very narrowed neck arteries have low risk of future stroke, study shows

The risk of having a future stroke caused by a severe blockage in an artery in the neck that is not currently causing any symptoms is so low that most patients with this condition -; asymptomatic carotid stenosis -; could potentially be treated with the newest medications and may not require surgery, new Kaiser Permanente research suggests.
