经颅多普勒对大脑中动脉急性脑梗死预后的预测作用

Predictive effect of Transcranial Doppler on prognosis of acute cerebral infarction of middle cerebral artery

目的:探讨大脑中动脉急性脑梗死未溶栓患者经颅多普勒超声的血流动力学分型对预后的预测作用。方法:研究大脑中动脉急性脑梗死患者60例,应用经颅多普勒将患者分为无闭塞组,部分闭塞组和完全闭塞组。在住院30 min、发病后第7、14天使用美国国立卫生研究院卒中量表评分,并且于发病后3个月行改良Rankin量表评分。结果:完全闭塞组和无闭塞组第7、14天神经功能缺损评分比较,差异有统计学意义(P<0.05)。闭塞组与无闭塞组发病3个月比较,差异有统计学意义(P<0.05)。结论:大脑中动脉脑梗死急性期患者应用经颅多普勒对病灶侧大脑中动脉血流动力学的分型,可预测大脑中动脉完全闭塞较无闭塞患者神经缺损程度显著。

Objective To investigate the predictive effect of Transcranial Doppler(TCD)on the prognosis of patients with middle cerebral artery acute cerebral infarction without thrombolysis.Method60patients with acute cerebral infarction of middle cerebral artery were studied.The patients were divided into non occlusion group,partial occlusion group and complete occlusion group by TCD.The National Institutes of Health Stroke Scale was administered for30minutes and seventh,fourteenth days after onset,and the modified Rankin scale was scored for3months after onset.Results There were significant differences in neurological deficit scores between the complete occlusion group and the non occlusion group for seventh,fourteenth days.The occlusion group and the non occlusion group were compared for3months after onset,the difference was statistically significant(P<0.05).Conclusion In the acute phase of middle cerebral artery cerebral infarction,the hemodynamics of the middle cerebral artery can be predicted by transcranial Doppler.The complete occlusion of the middle cerebral artery can be predicted,and the degree of nerve defect is obvious in the patients without occlusion.
