选择T2DM患者90例,用糖尿病足诊断箱中双向多普勒血流仪检测糖尿病患者的双侧胫后动脉压、足背动脉压、肱动脉血压。计算踝肱比值,ABI小于0.9提示PAD存在。结果ABI<0.9有17例,占18.89%。其中ABI<0.7有5例,占5.56%;双侧ABI<0.9有8例,占8.89%;单纯右侧ABI<0.9有5例,占5.56%;单纯左侧ABI<0.9有4例,占4.45%。与年龄、糖尿病病程及高血压病程呈现显著相关(P值<0.05),与性别无明显相关性(P值>0.05)。PAD与HbA1c、HDL-C呈相关(P值<0.05),与TC、TG、LDL-C无明显相关性(P值>0.05)。结论:多普勒(Doplix)超声检查测定ABI能客观准确显示PAD情况,T2DM PAD发生率较高,影响PAD发生的可能因素有年龄、糖尿病病程及高血压病程、HbA1c、HDL-C。
Totally 90 patients with T2DM were selected, and the bilateral posterior tibial arterial pressure, dorsalis pedis artery pressure and brachial artery blood pressure were measured by bidirectional Doppler flowmeter in diabetic foot diagnosis box. Calculate ankle brachial ratio, ABI less than 0.9 prompted the presence of PAD. Results There were 17 cases with ABI <0.9, accounting for 18.89%. There were 5 cases in ABI <0.7, accounting for 5.56%. There were 8 cases (8.89%) in bilateral ABI <0.9, 5 cases (5.56%) in ABI <0.9, 4 cases in simple left ABI <0.9 4.45%. There were significant correlations with age, duration of diabetes and duration of hypertension (P <0.05), but no significant correlation with gender (P> 0.05). PAD was correlated with HbA1c and HDL-C (P <0.05), but not with TC, TG and LDL-C (P> 0.05). Conclusion: Doplix ultrasonography can determine the severity of PAD objectively and accurately. The incidence of PAD in T2DM is high. The possible influencing factors of PAD are age, duration of diabetes, duration of hypertension, HbA1c and HDL-C.
