多普勒超声对老年2型糖尿病患者下肢血管病变的诊断准确性探讨

Diagnostic Accuracy of Doppler Ultrasound for Lower Limb Vascular Diseases of Elderly Patients with Type 2 Diabetes

目的 探究多普勒超声对老年2型糖尿病(T2DM)患者下肢血管病变的诊断准确性。方法 选取2022年6月—2023年8月本院收治的老年T2DM下肢血管病变患者及参加健康体检的人员各50例,分别将其设为观察组和对照组,予以多普勒超声检查,对比检查结果,判定多普勒超声诊断效果。结果 相较于对照组,观察组足背动脉、腘动脉、股动脉血管内径更小,且血流量数值更低,硬化斑块、管腔狭窄、管腔闭塞阳性检出率更高,差异有统计学意义(P<0.05);以综合诊断为标准,多普勒超声诊断准确率为98.00%,漏诊率为2.00%,两种方式诊断结果无明显差异(P>0.05)。结论 在老年T2DM患者下肢血管病变诊断中,多普勒超声诊断准确率较高,且具有重复性高、操作简便等应用优势。

Objective To explore accuracy of Doppler ultrasound in diagnosis of lower limb vascular diseases of elderly patients with type 2 diabetes(T2DM).Methods The paper chose 50 elderly T2DM patients with lower limb vascular lesions and 50 healthy individuals with physical examinations from June 2022 to August 2023,and divided them into observation group and control group,treated with Doppler ultrasound examinations,and compared results to determine diagnostic effect of Doppler ultrasound.Results Observation group had smaller inner diameters of dorsal foot artery,popliteal artery,and femoral artery,and lower blood flow values than control group.Positive detection rates of atherosclerotic plaques,luminal stenosis,and luminal occlusion were higher in observation group,difference was statistically significant(P<0.05).Based on comprehensive diagnosis,accuracy of Doppler ultrasound diagnosis was 98.00%,and missed diagnosis rate was 2.00%,with no significant difference in diagnostic results between two methods(P>0.05).Conclusion Doppler ultrasound can achieve high accuracy,high repeatability,and simple operation advantages in diagnosis of lower limb vascular lesions of elderly T2DM patients.
