二维彩色多普勒超声诊断下肢深静脉血栓的临床价值

Clinical Application Value of Color Doppler Flow Imaging on Diagnosing the Deep Venous Thrombosis in Lower Limb

目的:探讨二维彩色多普勒超声(CDFI)诊断下肢深静脉血栓(DVT)的临床价值。方法:对92例临床疑似下肢深静脉血栓病例行二维彩色多普勒超声检查,所有病例2周内均接受静脉造影或手术病理检查。结果:(1)92例疑似DVT患者中,CDFI检查阳性68例,阴性24例,其灵敏度为92.9%,特异性为90.5%,准确性为92.4%。(2)诊断正确的66例DVT中,左侧下肢52例,右侧下肢11例,双下肢2例。其中,髂-股静脉段21例(7例并大隐静脉起始部血栓),股-腘静脉段27例(9例并小隐静脉起始部血栓),单纯腘静脉内血栓10例。腘静脉-胫后静脉-肌间静脉-小隐静脉血栓8例。结论:CDFI诊断DVT准确,可靠,有重要的临床价值。

Objective：To Observe the clinical application value of Color Doppler Flow Imaging （CDFI） on diagnosing the deep venous thrombosis （DVT） in lower limb. Method：The 92 clinical doubtful cases of DVT were detected by CDFI, and then be diagnosed by phlebography or pathological detection in 2 weeks. Result：O） By using CDFI, the number of positive cases was 66, and the negative cases was 24. The diagnosis sensitivity was 92.9%, specificity was 90.5% and accuracy was 92.4%. （2） Of the 66 positive cases, 52 were in left lower limbs, 11 were in right lower limbs, 2 were in both lower limbs. 21 cases had thromboses in the external iliac veins and femoral veins, 7 also in the initiation of great saphenous veins. 27 cases had thromboses in the femoral veins and popliteal veins, 9 also in the initiation of small saphenous veins. 10 cases had thromboses only in popliteal veinss. 8 cases had thrombosis in the popliteal veins, posterior tibial veins, intersarco veins and small saphenous veins. Conelnsios;CDFl is an accurate and reliable technique on diagnosing the DVT.
