The main study outcome was recurrent stroke. Predictive factors were anterior circulation flow direction change (ACFDC), posterior circulation flow direction change, and reversal of ophthalmic artery\/leptomeningeal anastomosis (ROALA) detected by transcranial color\u2010coded duplex (TCCD) before carotid stenting. Patient follow\u2010up was 9\u2009years.
