Abstract: Objective To evaluate the effects and safety of stenting for posterior circulation ischemia resultedfrom large artry occclusive diseases.Methods Patients of posterior circulation ischemia resulted from large artry occclusive diseaseswere treated with stenting since March, 2003 in our hospital, and we took a retrospective study onthe effects and follow-up results. Total 86 patients enrolled in our study, 58 males and 28 females,mean age 61±5 year.Results Among the 86 patients, two cases were resulted by dissecting aneurysm of V3 segment ofleft vertebral artery, one case was resulted from dissecting stenosis of the origin of left vertebralartery and 83 cases were resulted from atherosclerotic artery stenosis. The successful rate ofstenting was 97.7%. After 22.5±10.5 months follow-up, we found 4 cases of anterior circulationinfarct, 3 cases of posterior circulation infarct, 2 cases of posterior circulation transient ischemiaattach(TIA), 2 cases of cerebral hemorrhage and 3 cases of death. The incidence rate of ischemicaccidents in posterior circulation was 5.95%.Conclusion Stenting may be an effective therapy in the management of stenosis and dissectinganeurysm of the vertebrobasilar artery, and it can prevent posterior circulation ischemia.
