急性缺血性脑血管病患者脑动脉粥样硬化的分布

摘要

Objective To direct the therapy and the prevention ofcerebrovascular disease,we analyzed the state and distribution of arteriosclerosis of intracranial and extracranial arteries in the patients with acute ischemic stroke.Methods The intracranial and extracranial arteries were checked by and Duplex.Results There were 75 cases (37％) with the stenosis of intracranial arteries and their branches and 50 cases (25％) with more than 50％ stenosis of extracranial arteries.12 case(6％) of patients had carotid occlusion.The diabetes is one of the risk factors of the stenosis of intracranial and extracranial arteries.Conclusion The main cause of ischemic stroke is stenosis of intracranail arteries,and more cases of stroke have abnormal extracranial arteries.%目的分析国内缺血性脑血管病人颅内外颈动脉粥样硬化的程度和分布，以指导脑血管病的治疗和预防。方法通过经颅和双功能彩色多普勒超声检测颅内外血管，检测动脉粥样硬化程度，并参照其病史、CT或MRI检查及生化指标综合分析。结果201例患者，颅内颈内动脉及分支狭窄75人，患病率为37％，颅外颈动脉大于50％狭窄的有50例，患病率为25％，其中12例为颈内动脉闭塞，患病率为6％，糖尿病是造成颅内外血管狭窄的危险因素之一。结论脑梗塞患者颅内血管病变是发病的原因之一，同时发现颅外血管病变日益增多。
