目的探讨彩色多普勒超声(CDFI)检查对老年人下肢动脉狭窄的诊断价值。方法对比分析CDFI和数字减影血管造影(DSA)对老年人下肢动脉狭窄的检查结果。结果 66例患者中,47例患者CDFI和DSA均诊断为下肢动脉狭窄,10例患者均诊断为无狭窄;3例DSA诊断为狭窄,CDFI无狭窄;6例CDFI诊断有狭窄,DSA无狭窄。以DSA检查结果为标准,CDFI诊断下肢动脉狭窄的敏感度为94.0%(47/50),准确度为86.4%(57/66)。结论 CDFI对老年下肢动脉狭窄性病变的诊断有其独特的优越性,它与DSA检查具有很好的的一致性,可作为评估老年人下肢动脉狭窄检查的首选方法。
Objective To investigate the diagnostic value of color Doppler ultrasonography (CDFI) in the diagnosis of lower extremity arterial stenosis in the elderly. Methods The results of CDFI and digital subtraction angiography (DSA) were compared between the lower extremity arterial stenosis in the elderly. Results Of 66 patients, 47 cases were diagnosed as arterial stenosis by CDFI and DSA, 10 cases were diagnosed as stenosis, 3 cases were diagnosed as stenosis by DSA, 7 cases were without stenosis by CDFI, 6 cases were stenosed by CDFI and stenosis was not found by DSA. According to the results of DSA, the sensitivity of CDFI in the diagnosis of lower extremity arterial stenosis was 94.0% (47/50) and the accuracy was 86.4% (57/66). Conclusion CDFI has unique superiority in diagnosis of stenosis of lower extremity arterial stenosis in elderly patients. It has good consistency with DSA and can be used as the first choice for the assessment of lower extremity arterial stenosis in the elderly.
