There is quite a bit of debate on this very topic at the moment, but some conclusions have been drawn: 1) carotid stents
are not worse (but not better) than carotid endarterectomy, 2) there appears to be a higher risk of stroke
with carotid stenting
in people older than 80 years as compared with endarterectomy, 3) stents reduce nerve injury
when a repeat carotid endarterectomy is needed.
