3 Fig 2 Regional variation in utilization of carotid artery stenting (CAS). Variation reflects the proportion of all carotid revascularization procedures that are CAS. Journal of Vascular Surgery  , 89-97DOI: ( /j.jvs ) Copyright © 2016 Society for Vascular Surgery Terms and Conditions

4 Fig 3 Change in the number of revascularizations by carotid endarterectomy (CEA; x-axis) and carotid artery stenting (CAS; y-axis) per 1000 Medicare beneficiaries performed from 2004 to 2010 for each of the 306 hospital referral regions (HRRs).

5 Fig 4 Annual number of carotid artery stents (CAS) placed by cardiologists, surgeons, and radiologists per 1000 Medicare beneficiaries from 2002 to The change in rate from 2002 to 2010 was statistically significant for each speciality (P < .001 for each).
