目的分析彩色多普勒超声诊断糖尿病足动脉血管早期病变临床价值。方法分析于2015年3月—2017年3月期间该院接收的120例(144支胫后动脉)糖尿病足动脉血管早期病变患者资料,均行CDFI与超声造影诊断,并将检测结果分别设为实验组与对照组,对比2组诊断准确性。结果实验组确诊率、假阳性率分别为96.66%、3.33%,对照组确诊率、假阳性率分别为100.00%、0.00%;实验组高估26支血管狭窄程度,低估12支血管狭窄程度:对照组高估6支血管狭窄程度,低估4支狭窄程度。结论 CDFI可作为临床诊断糖尿病足下肢动脉病变首选方案,但针对较难诊断患者,可结合超声造影获取信息补充,从而为临床医治提供重要依据,可被临床推广、应用。
Objective To analyze the clinical value of color Doppler ultrasonography in diagnosing early diabetic foot artery disease. Methods The data of 120 cases (144 posterior tibial arteries) of diabetic foot artery lesions received from March 2015 to March 2017 in our hospital were diagnosed by CDFI and contrast-enhanced ultrasonography and the results were set as The experimental group and the control group, compared with two groups of diagnostic accuracy. Results The diagnosis rate and false positive rate in the experimental group were 96.66% and 3.33% respectively. The confirmed and false positive rate in the control group were 100.00% and 0.00% respectively. The experimental group overestimated the degree of stenosis in 26 vessels and underestimated the degree of stenosis in 12 vessels: The control group overestimated the degree of 6 vascular stenosis and underestimated the degree of 4 stenosis. Conclusion CDFI can be used as the first choice for clinical diagnosis of diabetic lower extremity arterial disease. However, CDFI can be used in combination with CEUS to provide information for clinical treatment, which may be clinically promoted and applied.
