Abstract:
Objective To evaluate the diagnostic role of color Doppler ultrasonogarphy(CDU),Doppler ultrasound(DU)in the diagnosis of lower extremity deep venous thrombosis(DVT). Methods In this study,84 patients(92 lower extremities)of lower extremity DVT were underwent CDU and DU and lower extremity deep venous angiography respectively. Results Total consistent rate,sensitivity,specificity,omission diagnostic rate,mistake diagnostic rate,Youden index,Odd product.positive predictive value,negative predictive value and Kappa of CDU in diagnosing lower extremity DVT was respectively 96.7%,95.7%,97.8%,4.3%,2.2%,0.935,990.0,97.8%.95.7%and 0.935(P=0.037).As Kappa of CDU(0.935)＞0.75 and its P(0.037)＜0.05.CDU can theoreticallv substitute for deep venous angiography;Above-mentioned indexes of DU were respectively 89.1%,87.2%,91.1%,12.8%,8.9%,0.783,70.0,91.1%,87.2%and 0.783(P=0.065). Conclusion CDU iS becoming preferred and more reliable noninvasive method in diagnosing lower extremitv DVT.
