摘　　要：目的探讨超声弹性成像联合二维超声诊断下肢深静脉血栓(DVT)的价值。方法选取2020年1月—2022年12月合肥市第一人民医院收治的疑似下肢DVT患者100例为研究对象。回顾相关临床资料,比较一般资料、二维超声检查结果、下肢深静脉造影结果、超声弹性成像评分与应变值,并分析超声弹性成像联合二维超声诊断下肢DVT的价值。结果100例疑似DVT患者经下肢深静脉造影后确诊为DVT34例(DVT组),确诊为非DVT66例(非DVT组)。两组性别、体质量指数、高血压、糖尿病及高脂血症比较,差异均无统计学意义(P>0.05)。二维超声诊断DVT的敏感性为73.53%(25/34),特异性为92.42%(61/66);超声弹性成像诊断DVT的敏感性为82.35%(28/34),特异性为84.85%(56/66)。二维超声、超声弹性成像、超声弹性成像联合二维超声诊断DVT的敏感性分别为73.53%(95%CI:0.697,0.970)、82.35%(95%CI:0.589,0.862)、88.24%(95%CI:0.673,0.909),特异性分别为92.42%(95%CI:0.806,0.937)、84.85%(95%CI:0.823,0.958)、89.39%(95%CI:0.868,0.977)。结论超声弹性成像联合二维超声诊断下肢DVT的价值较高,可以在临床推广使用。Objective To explore the value of ultrasound elastography combined with two-dimensional ultrasound in the diagnosis of deep vein thrombosis(DVT)of lower limbs.Method A total of 100 suspected DVT patients admitted to the Ultrasound Department of Hefei First People's Hospital from January 2020 to December 2022 were selected as the research objects,and their related clinical data were reviewed.Their general data,two-dimensional ultrasound examination results and lower limb deep vein angiography results,ultrasonic elastography scores and strain values were compared,and the value of ultrasonic elastography combined with two-dimensional ultrasound in the diagnosis of lower limb deep vein thrombosis was analyzed.Result Among the 100 patients with suspected DVT,34 were diagnosed with DVT and 66 were diagnosed with non-DVT after deep venography of the lower extremities.Thirty-four patients with DVT were enrolled in the DVT group and 66 patients with non-DVT were enrolled in the non-DVT group.There was no significant difference in gender composition,body mass index,prevalence of hypertension,prevalence of diabetes mellitus and prevalence of hyperlipidemia between DVT patients and non-DVT patients(P>0.05).The sensitivity and specificity of two-dimensional ultrasound for the diagnosis of DVT were 73.53%(25/34)and 92.42%(61/66).The sensitivity and specificity of ultrasound elastography in the diagnosis of DVT were 82.35%(28/34)and 84.85%(56/66).The sensitivity,ultrasound elastography,and ultrasound elastography combined with two-dimensional ultrasound diagnosis were 73.53%(95%CI:0.697,0.970),82.35%(95%CI:0.589,0.862)and 88.24%(95%CI:0.673,0.909),respectively,and the specificity was 92.42%(95%CI:0.806,0.937),84.85%(95%CI:0.823,0.958),and 89.39%(95%CI:0.868,0.977).Conclusion Ultrasound elastography combined with two-dimensional ultrasound is of high value in the diagnosis of lower limb deep vein thrombosis and can be widely used in clinical practice.
