采用多普勒震动血流探测仪测定糖尿病患者足背动脉、胫后动脉与肱动脉的比值,以比值小于0.9为异常。结果本组100例患者中检出ABI<0.9者占34%。合并下肢动脉病变组与正常组比较,前者年龄大,病程长,餐后血糖、TG、LDL-C、吸烟率、DBP和HbA1C达标年明显降低。逐步回归分析显示,年龄、病程、TG、HbA1C是影响ABI的独立因素。结论是一项花费小、简单、无创的诊断下肢动脉病变的可靠指标。高龄、病程长、高TG、高血糖是加剧PAD的主要因素。
Doppler vibration flow detector was used to measure the ratio of dorsal artery, posterior tibial artery and brachial artery in patients with diabetes, and the ratio was less than 0.9. Results The group of 100 patients ABI <0.9 were detected in 34%. The lower extremity arterial disease group compared with the normal group, the former older, longer duration, postprandial blood glucose, TG, LDL-C, smoking, DBP and HbA1C markedly reduced the standard year. Stepwise regression analysis showed that age, duration of disease, TG and HbA1C were independent factors affecting ABI. The conclusion is a reliable, low-cost, simple and non-invasive diagnostic tool for lower extremity arterial disease. Elderly, long duration, high TG, high blood sugar is to aggravate the main factors PAD.
