Technical success rate was 100%, and the average s tenosis was reduced from (82.44±8.59)% to (4.19±3.23)%(P<0.01). No s erious compli cations happened in perioperative period. During the further clinical follow_upperiod from 3 months to 32 months(mean 20.8 months), 2 patients had recurrenceof symptoms, and the remaining patients had good effect and had no cerebral isch emic events.
