[摘要] 目的：探讨症状性大脑中动脉狭窄的预后和影响因素。方法：回顾性分析我院2005年1月～2009年6月收治的症状性大脑中动脉狭窄患者60例的临床资料。随机选择我院同期确诊的无症状性大脑中动脉狭窄的脑梗死患者60例作为对照组，并对两组患者进行分析。结果：符合入选条件的患者共37例，主要临床表现为头昏、头痛、头沉、反应迟钝、记忆力下降等。其中，左侧MCA狭窄者17例，右侧MCA狭窄者12例，双侧MCA狭窄者8例。卒中家族史、高血压、糖尿病是常见的危险因素，头颅CT异常者5例(13.5%)，主要为腔隙性脑梗死或交界区脑梗死。结论：大脑中动脉狭窄患者常存在脑血管病家族史、高血压、糖尿病等危险因素，可无典型的临床症状，但可存在无症状性脑梗死。

[Abstract] Objective: To discuss the prognosis and influencing factor of the symptom cerebrum median artery narrow. Methods: Retrospectively analyzed the clinical material of 60 patients with the symptom cerebrum median artery narrow which mycourtyard from January 2005 to June 2009. Random selection of 60 patients with the symptomless cerebrum median artery narrow cerebral infarction which my courtyard diagnoses same time to take the control group, and carried on the analysis to two group of patients. Results: Conforms to the selected condition patient altogether 37 cases, the main clinical manifestation for dizziness, the headache, sinks, the slow reaction, the memory drop and so on. And left side MCA narrow 17 cases, right flank MCA narrow 12 cases, two-sided MCA narrow 8 cases. The apoplexy family history, hypertension sickness, diabetes were the common hazard factors, CT unusuality 5 cases (13.5%), were mainly the cavity crack cerebral infarction or the border area cerebral infarction. Conclusion: The cerebrum median artery narrow patient is everlasting in the cerebrovascular disease family history, hypertension sickness, diabetes and so on hazard factor, may not have the model clinical symptoms, but may have the symptomless cerebral infarction.

动脉硬化引起脑血管腔内狭窄是引起脑血栓形成的主要原因，而颅内血管狭窄以亚洲人最常见，尤其在大脑中动脉，颅内动脉狭窄是缺血性卒中的一个重要原因，而大脑中动脉狭窄的患者每年卒中的发生率为7.0%～17.7%[1]。大约10%的缺血性卒中及8%的短暂性脑缺血发作(TIA)是由此引起的，而黄种人这个比例可能还要更高。长期以来抗血小板、调脂等内科疗法一直被认为是治疗缺血性脑卒中的有效的治疗方法 ......
