糖尿病患者颈动脉彩超检测的应用价值

Application of Colour Doppler Ultrasound Used for Carotid Artery in Diabetes Mellitus Patients

目的 应用彩色多普勒超声检测Ⅱ型糖尿病患者颈动脉病变情况。方法 对117例糖尿病患者双侧颈动脉检测结果与对照组127例健康人群进行比较分析。结果 糖尿病组Ⅲ级粥样斑块检出率(44.4％)与对照组(9.6％)有明显差异(P<0.01);糖尿病组血流速度降低、血管阻力指数及搏动指数增高,与对照组存在差异(P<0.05)。结论 糖尿病患者颈动脉病变以粥样硬化斑块形成、血流减速、血管阻力增高为主要特点。彩超可直观反映病变的分期、轻重程度,在糖尿病血管病变的诊断中具有重要的实用价值。

Objective To exam diseases of carotid artery of type Ⅱ diabetes Mellitus patients by Colour Doppler Ultrasound. Methods Carotid artery ultrasonography in 117 diabetes and compared with 127 normal controls. Results In type Ⅱ diabetes mellitus patients, the stage Ⅲ of carotid atherosclerotic plagues have pobvious difference as compared with the control group(P < 0.01), there have statistical difference in the blood velocity decreasing , resistance index(RI) and pulsative index(PI) increasing between the group of diabetes and control group( P < 0. 05). Conclusion It is main feature that formed carotid atherosclerotic plagues, blood velocity decreasing, resistance and pulsatie index increasing in carotid artery of diabetes mellitus patients. For diabetes mellitus patients, Colour Doppler can directly reflect different degree of the diseases , so it is of important value in diagnosis of blood vessel.
