Fig 1 A, The scoring system for anatomic suitability for carotid artery stenting (CAS). B, Patient-specific cases selected according to this scoring system are classified as (left) green, (middle) amber, and (right) red. CCA, Common carotid artery; ECA, external carotid artery; ICA, internal carotid artery.

Fig 2 Outcomes of carotid artery stenting (CAS) on the virtual reality simulator are shown. A, Procedure time (left) and fluoroscopy time (right) for each case. B, Contrast use (left) and number of angiographies (right) for each case. C, Qualitative performance of each case, as measured by the Global Rating Scale (GRS) (left) and Procedure Specific Rating Scale (PSRS) (right). The horizontal line in the middle of each box indicates the median; the top and bottom borders of the box mark the 75th and 25th percentiles, respectively, and the whiskers mark the 90th and 10th percentiles; the black circles indicate outliers; and the dotted lines in C represent arbitrary level of competent performance.
