Abstract:
Objective:To evaluate the safety,feasibility and long-term result of stent placement for vertebral artery (VA) stenosis of outer cranial segment. Methods:40 patients with vertebral artery of outer cranial segment stenosis were treated with stenting. Results:Carotid artery stents were placed in 4 patients and both side vertebral artery stents were placed in 2 patients simultaneously. 46 stents were used in total. The achievement ratio of operation was 100%. During the further follow up period of average 18 months,6 patients accepted recheck of DSA,2 of whom developed restenosis.The stenosis ratios were 10% and 15% respectively. None develop posterior circulation ischemia. Conclusion:Stent placement for treatment of atherosclerotic stenosis of vertebral artery of outer cranial segment is technically feasible and effective,which could be the choice of secondary prevention for cerebrovascular disease.
