彩色多普勒超声对下肢血管狭窄性疾病的诊断研究

A Study on the Diagnosis of the Lower Extremity Vascular Stenosis bythe Color Doppler Ultrasound

目的:探讨彩色多普勒超声对下肢血管狭窄性疾病的诊断研究。方法:选取59例患者作为本次研究对象,所有患者均采用多普勒超声技术检查、数字减影血管造影(DSA)技术检查,彩色多普勒超声检查结果与DSA检查结果进行比较,分析彩色多普勒超声检查的特异度和灵敏度。结果:患者下肢血管闭塞的节段数116节,重度狭窄22节,中度狭窄52节,轻度狭窄57节,彩超检查与DSA检查符合率分别为89.922%、68.750%、76.470%、89.815%。结论:下肢血管狭窄性疾病采用彩色多普勒超声检查有无创、简便、可重复、安全等多种优势,且准确率较高,值得临床推广。

Objective:To explore the diagnostic study on the lower extremity vascular stenosis by the color Doppler ultrasound.Methods:59 patients were selected as the object of this study,all the patients were given the color Dopplerultrasound and the digital subtraction angiography(DSA).The results of the color Doppler ultrasound and the DSA were compared,the specificity and sensitivity of the color Dopplerultrasound were analyzed.Results:The patients were found that they had 116 vessels with vascular occlusion,22 with severe stenosis,52 with moderate stenosis and 57 with mild stenosis of their lower extremity,the coincidence rate of the color Doppler ultrasound and the DSA were 89.922%,68.750%,76.470% and 89.815%,respectively.Conclusion:The adoption of the color Doppler ultrasound in the diagnosis of the lower extremity vascular stenosis is non-invasive,simple,repeatable and safe,with highly accuracy,and it’s worth being promoted in the clinical application.
