Restenosis after carotid endarterectomy in a multicenter regional registry

In our region, restenosis after CEA, especially clinically significant restenosis ≤1 year after surgery, decreased slightly over time. This improvement in outcome was associated with several factors, including an increase in patching after conventional CEA, a process of care that was studied and encouraged within our vascular study group. These results highlight the utility of regional quality-improvement efforts in improving outcomes in vascular surgery.
