【摘要】：目的探讨256-CT下肢动脉造影(256-multiple slice CT angiography,256-MSCTA、彩色多普勒超声(doppuler ultra sound,DUS)、)两种方法在糖尿病下肢血管病变(lower extremities arterial disease,LEAD)的中应用价值。方法 50例DSA确诊2型糖尿病下肢动脉病变患者,2周内行256-CTA及DUS检查,分析DLEAD病变特点,各段血管以DSA为金标准,计算两种检查方法敏感度、特异度、阳性预测值、阴性预测值、诊断符合率。结果 1.256-CTA与DUS对下肢动脉狭窄总体检出率无统计学差异(P0.05),对膝下血管组阳性检出率256-CTA优于DUS,差异有统计学意义(P0.05),2.256-CTA在LEAD的评估中,与DSA对比灵敏度、特异度、诊断符合率均较高。结论256-CTA对糖尿病下肢动脉病变的诊断和评估中,灵敏度、特异度较高,对膝下动脉狭窄诊断优于DUS。
[Abstract]:Objective to investigate the value of 256-multiple slice CT angiography256-MSCTA (color Doppler ultra sound) in lower extremities arterial disease of lower extremity diabetic patients with diabetes mellitus. Methods 50 patients with type 2 diabetes mellitus were diagnosed by DSA. The patients underwent 256-CTA and DUS within 2 weeks. The characteristics of DLEAD lesions were analyzed. The sensitivity, specificity, positive predictive value, negative predictive value of the two methods were calculated by using DSA as the gold standard. Results there was no significant difference between 1.256-CTA and DUS in the detection rate of lower extremity arterial stenosis (P 0.05). The positive rate of 256-CTA in the subgenu artery group was better than that of DUS.The difference was statistically significant in the evaluation of LEAD between 1.256-CTA and DUS. The sensitivity and specificity were compared with DSA. Conclusion the sensitivity and specificity of 256-CTA in the diagnosis and evaluation of diabetic lower extremity arterial lesions are higher, and the diagnosis of inferior genu artery stenosis is superior to that of DUSS.
