Defining the threshold surgeon volume associated with improved patient outcomes for carotid endarterectomy

ObjectiveThe outcomes for common vascular operations, such as carotid endarterectomy (CEA), are associated with surgeon volume. However, the number of operations associated with an improved stroke or death rate for CEA is not known. The objective of the current study was to define the annual surgeon volume of CEAs that is associated with a lower risk of stroke or death rate.MethodsThe Nationwide Inpatient Sample was analyzed to identify patients...
