彩色多普勒超声诊断下肢深静脉血栓形成的临床效果

Clinical effect of color Doppler ultrasound in the diagnosis of deep venous thrombosis

目的探讨彩色多普勒超声在下肢深静脉血栓(DVT)形成中的诊断价值。方法选取我院收治的DVT患者60例作为观察组,选择同期体检的60例健康者作为对照组。两组受检者均接受彩色多普勒超声诊断,观察组同时接受数字减影血管造影(DSA)检查。比较两组受检者的血管内径及血流速度,分析观察组患者经彩色多普勒超声检查的的诊断符合率及血管异常特征检出情况。结果观察组60例患者经DSA检出DVT 69条,彩色多普勒超声诊断检出65条,彩色多普勒超声的诊断符合率为94.2%。观察组CFV、SFV、POV血管内径及血流速度均明显低于对照组(P<0.05)。观察组患者经彩色多普勒超声检出的DVT 65条中,存在血管内膜异常35条(53.84%),瓣膜功能不全26条(40.00%),血管内回声异常56条(86.15%)。结论彩色多普勒超声诊断下肢深静脉血栓能够准确显示血管内血流异常、血管异常特征等,具有较高的临床价值。

Objective To investigate the diagnostic value of color Doppler ultrasound in the diagnosis of deep venous thrombosis(DVT). Methods Sixty DVT patients admitted in our hospital were selected as the observation group, and 60 physical examiners at the same period were enrolled as the control group. All the examiners received color Doppler ultrasound detection, and the observation group added digital subtraction angiography(DSA) detection. The blood vessel diameter and blood flow velocity of the two groups were compared, and the diagnostic coincidence rate and the detection of abnormal vascular characteristics of the patients in the observation group by color Doppler ultrasound were analyzed. Results There were 69 vessels with DVT in the observation group by DSA, 65 vessels were detected by color Doppler ultrasound,and the coincidence rate of color Doppler ultrasound was 94.2 %. The CFV, SFV and POV blood vessel diameter and blood flow velocity of the observation group were lower than those of the control group(P<0.05). In 65 vessels diagnosed as DVT by color Doppler ultrasound of the observation group, there were 35 vessels(53.84%) of abnormal intima, 26 vessels(40.00%) of valve insufficiency and 56 vessels(86.15%) of intravascular echo was abnormal. Conclusion Color Doppler ultrasound in the diagnosis of DVT can accurately display the abnormal blood flow and the characteristics of vascular abnormalities, which has significant clinical value.
