Does carotid artery stenting increase the risk of restenosis compared to carotid endarterectomy?
Carotid artery stenting is associated with an approximately 2.5-fold higher short-term risk of moderate restenosis or occlusion compared to carotid endarterectomy.
The short-term rate of carotid restenosis of ≥50% or occlusion is ≈2.5-times more common after CAS than after CEA, a difference accounted for by an excess risk in moderate restenosis. More data with longer follow-up are needed to assess the rates of late severe restenosis and to determine the relation between restenosis and recurrent stroke over time.
