According to a 30-day outcomes report from the Society for Vascular Surgery (SVS) Vascular Registry for Carotid Procedures, In patients with carotid artery disease, Carotid endarterectomy (CEA) yields better short-term results than carotid artery stenting (CAS). Carotid artery disease is marked by stenosis of the carotid artery, located on either side of the neck that supplies blood to the brain. Normally, this has been treated by performing an open repair surgery (CEA). An endovascular procedure (CAS) treats patients those who are at risk for complications such as prior carotid artery surgery (i.e., CEA), exposure to radiation at the neck or neurological conditions (i.e., prior stroke). The SVS Outcomes Committee developed the Vascular Registry for Carotid Procedures in response to the 2005 Centers for Medicare and Medicaid Services National Coverage Decision on carotid artery stenting. The SVS Vascular Registry went live on July 2005, as the first societal registry to enroll CAS and CEA patients. Data are allocated to visit intervals of 30-day, six-month, one-year, and subsequent annual evaluations. Dr. Sidawy added that after risk-adjustment for history of stroke, age, diabetes and the American Society of Anesthesiologists' grade that is factors found to be significant confounders in outcomes using backwards elimination, logistic regression analysis suggested better outcomes following CEA. In the case of treatment of atherosclerotic disease only, when CAS and CEA were compared, the difference in outcomes between the two procedures was more pronounced, with death/stroke/MI 6.42 percent after CAS vs. 2.62 percent following CEA, p
