2型糖尿病合并脑血管病脑血管的彩色多普勒研究

The Study of Transcranial Color Doppler Ultrasound of Cerebral Vessel of Type 2 Diabetes Patients with Cerebrovascular Disease

目的 探讨经颅彩色多普勒超声评价 2型糖尿病合并脑血管病患者脑血管病变的价值 ,寻求一种对 2型糖尿病合并脑血管病的简单、无创、可靠、重复性能好的诊断方法。方法 对 40例 2型糖尿病患者及 40例健康人进行经颅彩色多普勒超声 ,根据不同的病程将患者分成三组 ,并与对照组 40例健康人进行对照。结果 2型糖尿病脑血管病损害的主要表现是脑动脉硬化 ,可分为五种类型 :①正常血流速度型 ;②脑动脉硬化加速型 ;③脑动脉硬化减速型 ;④脑动脉狭窄流速加快型 ;⑤脑动脉狭窄减速型。结论 经颅彩色多普勒血流图可以反映 2型糖尿病患者脑血管的病变的程度及血流动力学变化 ,并对其并存的脑动脉硬化作出诊断 。

Objective To evaluate the value of transcranial color Doppler ultrasound (TCCD) in diagnosis of cerebrovascular disease of type 2 diabetes patients. Methods 40 cases of type 2 diabetes and 40 healthy people had TCCD examination. Results The main appearance of cerebrovascular lesion of type 2 diabetes patients was atherosclerosis. It could be divided into 5 types on TCCD: ①normal velocity of blood flow type; ②atherosclerosis with accelerate velocity type; ③atherosclerosis with slow velocity type; ④cerebrovascular stenosis with accelerate velocity type; ⑤cerebrovascular stenosis with slow velocity type. Conclusion TCCD can accurately diagnosis the cerebrovascular disease of type 2 diabetes patients by evaluating the hemodynamic changes of cerebral vessels.
