脑梗死患者颈动脉与颅内动脉血流的临床研究

目的:探讨脑梗死患者颈动脉内中膜厚度、粥样硬化斑块的形成及颅内动脉血流动力学改变与糖尿病之间的关系.方法:116例大脑中动脉供血区脑梗死患者根据有无合并糖尿病分为脑梗死无糖尿病组(74例)及脑梗死合并糖尿病组(42例),并以40例健康者作为对照组,所有观察对象分别进行颈动脉彩色多普勒(CDFI)及经颅多普勒(TCD)检查,测量颈动脉内中膜厚度(IMT),观察管壁有无斑块及斑块的性质,记录颅内动脉血流参数.结果:糖尿病组颈动脉内-中膜厚度及颈动脉斑块发生率分别与非糖尿病组和对照组比较,有显著性差异(P<0.05),大脑中动脉血流情况3组间也存在差异(P<0.05).结论:糖尿病是造成脑梗死患者颈动脉内中膜增厚及粥样硬化斑块形成的主要危险因素,同时影响颅内血流情况,彩色多普勒及经颅多普勒联合检测对预防脑梗死的发生、判断预后、指导早期治疗具有重要作用.

Clinical study on blood hemodynamics of carotid artery and intracranial arteries in patients with cerebral infarction

Objective:To investigate the relationship between the intima media thickness(IMT) of carotid artery for the cerebral infarction patients and carotid atheromatous plaque and change of intracranial arteries hemodynamics and diabetes mellitus.Methods:116 cases of cerebral infarction patients in blood supply from MCA were divided into two groups as cerebral infarction with diabetes group and cerebral infarction without diabetes group.40 health people were selected as control group.All were examined by using col...
