目的研究糖尿病与动脉硬化性血管障碍的关系。方法对60例糖尿病患者及60例非糖尿病患者进行超声检查，观察两侧下肢动脉内径（D）、内膜一中层厚度（IM）、收缩期最高速度（Max）、舒张期速度（Min）、搏动指数（PI）、阻力指数（RI）及有无斑块形成，进行统计。结果IMT糖尿病组较非糖尿病纷增厚（P＜0．01），各项血流参数在糖尿病组与非糖尿病织间差别无显著性（P＜0.05）。结论下肢动脉的IMT与动脉粥样硬化的程度有关，应用超声进行观察，可以判断糖尿病下肢动脉硬化的进展情况、治疗效果及预后。
Objective To study the relationship between diabetes and arteriosclerotic vascular disorders. Methods Sixty diabetics and sixty nondiabetic patients underwent ultrasonography to observe the arterial diameter (D), intima-media thickness (IM), systolic velocity (Max), diastolic velocity (Min) Pulsatility index (PI), resistance index (RI) and the presence or absence of plaque formation, statistics. Results Compared with non-diabetic patients, IMT diabetes group had thicker (P <0.01). The blood flow parameters had no significant difference between diabetic group and non-diabetic tissue (P <0.05). Conclusion IMT of lower extremity artery is related to the degree of atherosclerosis. Ultrasound can be used to judge the progress of arteriosclerosis, therapeutic effect and prognosis of lower extremity.
