How have the procedural risks of stroke or death following carotid endarterectomy and carotid artery stenting changed over time?
The procedural safety of carotid endarterectomy has improved over time, while the safety of carotid artery stenting has remained unchanged.
Risks of procedural stroke/death following CEA appear to have decreased substantially. There was no evidence of a change in stroke/death rates following CAS.
