Effect of carotid artery stenting surgery combined with nimodipine on cerebral anterior circulation hemodynamics

ObjectiveTo evaluate the effect of carotid artery stenting combined with nimodipine on cerebral hemodynamics by comparing and analyzing the change of anterior cerebral blood flow before and after treatment through transcranial Doppier (TCD).MethodsTwenty patients with ischmie cerebrovascular 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.ResultsAfter treatment, TCD examination showed dynamic changes in blood flow significantly. Ipsilateral 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.ConclusionCarotid artery stenting combined with nimodipine treatment can cause anterior cerebral hemodynamic changes in ipsilateral hemisphere and significantly improve blood flow.
