Methods Twenty patients with ischemic cerebrovascnlar disease were detected in blood flow velocity of bilateral middle cerebral arteries (MCA) and anterior cerebral arteries (ACA) and artery pulsatility index with TCD before and two weeks after treatment. Results After treatment, TCD examination showed dynamic changes in blood flow significantly, lpsilateral MCA flow velocity significantly increased; ipsilateral ACA flow velocity did not change significantly; there was no significant increase in the contralateral MCA flow velocity; flow rate decreased significantly in contralateral ACA. Conclusion Carotid artery stenting combined with nimodipine treatment can cause anterior cerebral hemodynamic changes in ipsilateral hemisphere and significantly improve blood flow展开更多
