目的：分析老年2型糖尿病(T2DM)患者下肢血管病变多普勒超声特征。方法选择62例老年T2DM患者为观察组，同期健康志愿者62例为对照组，均行双下肢彩色多普勒超声检查，观察老年T2DM患者下肢血管病变的超声表现，比较混合性斑块及纤维性斑块发生率，以及两组的下肢血管内膜厚度及血流参数。结果观察组下肢血管混合性斑块、纤维性斑块及斑块总发生率分别为29.0%、41.9%和70.9%，均明显高于对照组(P<0.05)；观察组股动脉及腘动脉内膜厚度(IMT)分别为(0.87±0.25) mm和(0.78±0.18) mm，均明显厚于对照组，但股动脉及腘动脉收缩期峰值流速(PSV)和加速度(Acc)均明显低于对照组，差异均有统计学意义(P<0.05)。结论老年2型糖尿病患者下肢动脉病变发生率高，多普勒频谱参数与健康志愿者比较差异有统计学意义。

Objective To analyze the ultrasonic characteristics of elderly type 2 diabetes mellitus (T2DM) patients with lower extremity vascular disease. Methods Sixty-two elderly patients with T2DM were chosen as the observation group, and 62 healthy volunteers were selected as the control group, which all underwent bilateral lower limbs by color Doppler ultrasonography. The ultrasonic characteristics of lower extremity vascular diseases of the el-derly patients with T2DM were observed. The incidence of mixed plaques and fibrous plaque, lower extremity vascu-lar intimal thickness (IMT), and blood flow parameters of two groups were compared. Results The incidence of mixed plaque, fibrous plaque and plaque in the observation group were 29.0%, 41.9%and 70.9%, significantly higher than those in the control group (P<0.05). The femoral artery and popliteal artery IMT in observation group were (0.87± 0.25) mm and (0.78 ± 0.18) mm, significantly thicker than those in the control group, but the peak systolic velocity (PSV), accelerated speed (Acc) of femoral artery and popliteal artery in the observation group were significantly lower than those in the control group (P<0.05). Conclusion Elderly patients with type 2 diabetes mellitus have significant-ly higher incidence of peripheral arterial disease, and there are significant differences in Doppler spectrum parameters between T2DM patients with lower extremity vascular diseases and health volunteers.
