回顾资料完整的2型糖尿病病历105例,根据脉冲多普勒测定的ABI分组(ABI≤0.9为I组,ABI>0.9为II组),观察踝部动脉频谱波形、峰值流速的变化,彩色多普勒超声对下肢动脉病变发现率,及ABI与性别、年龄、BMI、血压,HbA1c、糖尿病病程、血脂、尿酸等的关系。结果ABI与动脉频谱波形吻合很好,且有统计学意义。ABI与峰值流速吻合度不高。彩色多普勒超声提示下肢动脉硬化的发现率I组高于II组,差异有显著性意义,ABI>0.9组也有58.2%患者发现动脉硬化或斑块。年龄、糖化血红蛋白、胆固醇在ABI不同的两组中是有区别的I,组大于II组,差异有统计学意义。结论多普勒频谱波形变化是发现PAD的一个有价值的线索,峰值流速则是一个多变的参数,彩色多普勒超声发现的下肢动脉病变早于ABI。
The data of complete type 2 diabetes mellitus were retrospectively reviewed in 105 cases. According to the ABI group (ABI≤0.9 for group I and ABI> 0.9 for group II) by pulsed Doppler echocardiography, the change of peak arterial waveform and peak velocity in ankle were observed. The detection rate of arterial lesions in lower extremities by Doppler ultrasound and the relationship between ABI and sex, age, BMI, blood pressure, HbA1c, duration of diabetes, blood lipids, uric acid and so on. Results The ABI was in good agreement with the arterial spectrum waveform and had statistical significance. ABI and peak flow rate is not high agreement. Color Doppler ultrasound showed the detection rate of lower extremity arteriosclerosis in group I was higher than that in group II, the difference was significant, ABI> 0.9 group also found arteriosclerosis or plaque in 58.2%. Age, glycosylated hemoglobin, cholesterol in different ABI different groups are different I, the group is greater than the II group, the difference was statistically significant. Conclusion The change of Doppler spectral waveform is a valuable clue to find PAD. The peak flow rate is a variable parameter. The lower extremity arterial lesion detected by color Doppler ultrasound is earlier than ABI.
