An externally validated robust risk predictive model of adverse outcomes after carotid endarterectomy

The internally validated VSGNE CEA risk model, which robustly predicted adverse outcome after CEA, was externally validated by testing it against the remainder of VQI patients who underwent CEA by a diverse array of physicians. This tool provides a simple and reliable method to risk-stratify CEA patients using only their preoperative conditions. A risk score based on this model can reliably stratify patients according to their risk of adverse outcomes after CEA.
