•• In an analysis of 13,564 (weighted n=67,344) carotid artery stenting procedures, annual operator volume was associated with significantly lower rate of mortality and complications. Furthermore, a higher annual operator volume was associated with shorter length of hospital stay and lower hospitalization costs.
