Abstract:
Objective To explore the value of color Doppler ultrasonography and plasma D-dimer in diagnosis of lower limb deep venous thrombosis (DVT).Methods The clinical data of 70 cases of patients with lower limb DVT diagnosed clinically were retrospectively studied.The lower limb venous of each patient was examined by color Doppler ultrasonography and the plasma level of D-dimer were measured,furthermore the plasma levels of D-dimer in different phase and different type of thrombosis were compared.Results The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of plasma D-dimer and ultrasonography examination in lower limb DVT were 100%,66.7%,97.0%,100%,and 97.1%,and 98.4%,83.3%,98.4%,83.3%,and 97.1%,respectively.The plasma D-dimer in acute phase 〔(6 451?4 012.22) ?g/L〕 and subacute phase 〔(2 063?1831.35) ?g/L〕 of lower limb venous thrombosis were significantly higher than that in normal control group 〔(310?66.70) ?g/L〕,P
