与DSA对照评价ABI指数在糖尿病下肢血管病变中的诊断价值

ABI detection in the diagnosis of lower limb vasculopathy in the diabetes:a comparative study with DSA

目的:探讨测定踝-肱指数(Ankle brachial index,ABI)在糖尿病患者下肢血管病变中的诊断价值。方法:对44例怀疑糖尿病下肢血管病变患者进行ABI指数测定及X线数字减影血管造影(Digital subtraction angiography,DSA),并将检查得到的患肢分级情况及各段相应血管的病变相关结果比较。结果:患肢根据ABI指数分级,并与DSA结果进行比较,发现ABI指数分级与DSA检查结果无明显统计学差异,ABI的准确度87.31%,敏感度86.46%,特异度82.00%。结论:ABI指数检查在准确度、敏感度及特异度方面均能较好反映糖尿病下肢血管病变。

Objective：To explore the diagnostic value of ABI detection in lower limb vasculopathy of diabetic patients.Methods：ABI detection was performed in 44 cases suspected of diabetic lower limb vasculopathy,and the results were compared with that of DSA. Results：There was no statistically significant difference between ABI detection and DSA in the diagnosis of diabetic lower limb vasculopathy.Compared with DSA,the accordance rate,sensitivity and specificity of ABI were 87.31%,86.46%and 82.00%respectively. Conclusion：By ABI detection,lower limb vasculopathy of diabetic patients can be detected.
