【摘要】 目的:探讨3.0T 3D-TOF法MRA在分析脑梗死患者颅内动脉狭窄、闭塞的分布及特点中的应用。方法:对71例临床诊断为脑梗死的患者行3.0T 3D-TOF法MRA检查,分析脑梗死患者颅内动脉狭窄、闭塞的分布特点,并按梗塞灶类型及年龄分组,分析不同类型梗塞灶及不同年龄组脑梗死患者颅内动脉狭窄、闭塞的程度及分布特点。结果:71例脑梗死患者有动脉狭窄者54例54/71(76.1%),狭窄动脉分布:前循环动脉狭窄、闭塞28/54(51.9%);后循环动脉狭窄、闭塞10/54(18.5%);合并前、后循环动脉狭窄、闭塞16/54(29.6%)。腔隙性脑梗死组发现颅内动脉狭窄或闭塞25/37(67.6%);非腔隙性脑梗死组发现颅内动脉狭窄或闭塞29/34(85.3%)。老年组患者单一前循环动脉狭窄、闭塞较青中年组有所减少,而后循环动脉狭窄、闭塞和多发动脉狭窄、闭塞明显增加,多于青中年组(P<0.05);颅内动脉病变的程度与年龄成正相关。结论:颅内动脉狭窄、闭塞是脑梗死的重要发病基础,前循环较后循环多见。非腔隙性脑梗死患者颅内动脉狭窄、闭塞的发生率明显高于腔隙性脑梗死患者。不同年龄的脑梗死患者颅内动脉狭窄、闭塞的分布不同,血管病变的程度与年龄成正相关。3.0T 3D-TOF法MRA能够为脑梗死患者的临床治疗提供指导依据。更多还原

【Abstract】 Objective:To explore the application of 3.0T 3D-TOF MRA in analyzing the distribution and characteristics of intracranial artery stenosis or occlusion in the patients with cerebral infarction.Methods:Seventy-one patients with cerebral infarction were examed by 3.0T 3D-TOF MRA.The distribution and characteristics of intracranial artery stenosis or occlusion was analyzed.The patients were divided into different groups by the type of the range of infraction and different age,the distribution and characteristics of intracranial artery stenosis or occlusion of the different the range of infraction and different age were analyzed.Results:Of totally seventy-one patients with cerebral infarction,there were fifty-four patients with intracranial artery stenosis or occlusion(54/71,76.1%).The distribution of intracranial artery stenosis or occlusion:there were twenty-eight patients in fore cerebral circulation(28/54,51.9%),there were ten patients in post cerebral circulation(10/54,18.5%),and there were sixteen patients both in fore and post cerebral circulation(16/54,29.6%).The patients of intracranial artery stenosis or occlusion were twenty-five in the lacunar infraction group(25/37,67.6%).,and there were twenty-nine in the non-lacunar infraction group(29/34,85.3%).In the patients of young-middle aged group ,the proportion of intracranial artery stenosis or occlusion.was high.I n contrast,the proportion of intracranial artery stenosis or occlusion was lower in the old aged group .The degree of intracranial artery stenosis or occlusion varies with age.Conclusion:Intracranial artery stenosis or occlusion is the pathogenic basis of cerebral infarction,the stenosis or occlusion incidence rate in fore cerebral circulation was higher than that of the post cerebral circulation.The incidence rate of intracranial artery stenosis or occlusion in the non-lacunar infraction group was higher than that of lacunar infraction group.The distribution of intracranial artery stenosis or occlusion in patients with cerebral infarction differs among different groups of patients,the degree of intracranial artery stenosis or occlusion varies with age.3D-TOF MRA can provide theoretical support for the patients with cerebral infarction.更多还原
