彩色多普勒超声诊断下肢深静脉血栓形成的临床价值

Clinical Value of Color Doppler Ultrasound in Diagnosis of Deep Vein Thrombosis in Lower Limbs

目的:探讨彩色多普勒超声(CDUS)诊断下肢深静脉血栓形成(DVT)的临床价值。方法:选取2019年10月—2021年10月成武县人民医院收治的44例超声科检查疑似DVT患者作为研究对象,均实施数字减影血管造影(DSA)、CDUS检查。观察两种检查方式下DVT分布情况,以DSA检查为金标准,分析CDUS诊断DVT的价值及其与DSA检查的一致性。结果:DSA共检出血栓41条,DCUS共检出40条;CDUS诊断DVT的敏感度为97.56%(40/41),特异度为66.67%(2/3),阳性预测值为97.56%(40/41),准确度为95.45%(42/44),阴性预测值为66.67%(2/3);CDUS检查DVT结果与DSA检查的一致性尚可(kappa值=0.642,P=0.000)。结论:CDUS诊断DVT具有较高的准确度、敏感度,可为临床诊治提供参考依据。

Objective:To explore the clinical value of color Doppler ultrasound(CDUS)in the diagnosis of lower limb deep vein thrombosis(DVT).Methods:A total of 44 suspected DVT patients examined in the Ultrasonic Department of Chengwu County People's Hospital from October 2019 to October 2021 were selected as the study subjects.All the patients were examined by digital subtraction angiography(DSA)and CDUS.The DVT distribution under the two examination methods was observed,and DSA examination was used as the gold standard to analyze the diagnosis value of the DVT by CDUS and its consistency with the DSA examination.Results:A total of 41 thrombi were detected by DSA and a total of 40 thrombi were detected by DCUS;The sensitivity of CDUS for the diagnosis of DVT was 97.56%(40/41),the specificity was 66.67%(2/3),the positive predictive value was 97.56%(40/41),the accuracy was 95.45%(42/44),and the negative predictive value was 66.67%(2/3).The consistency in DVT results between CDUS examination and DSA examination was acceptable(kappa value=0.642,P=0.000).Conclusion:CDUS has a high accuracy and sensitivity for the diagnosis of DVT and can provide reference for clinical diagnosis and treatment.
