ObjectiveTo explore the application value of high freuency two-dimensional and
color Doppler ultrasonography in the
detection of
lower limb deep venous thrombosis.MethodsEighty-nine
patients with suspicious
lower limb deep venous thrombosis were enrolled and received high frequency two-dimensional and
color Doppler ultrasonography examination.Vessel diameter,
thrombus position,size and echo and
blood flow in vessel were observed.ResultsIn 89
patients,42 cases (47.2%) had femoral-
iliac vein thrombus;27 cases(30.3% ) had
vein thrombus in intramuscular of cnemis; 13 cases (14.6%) had
deep venous thrombosis of the whole
lower limbs; 5 cases (5.6%) had intramuscular haematoma;2 cases (2.2%)had subcutaneous soft
tissue edema of cnemis.Eighty-four cases were detected having
vein thrombus,2 cases (2.4%) were in both
lower limbs; 57 cases (67.9%) were in single left
lower limb and 25 cases(29.8%)were in single right
lower limb.The ratio between
thrombus in single left
lower limb and in single right
lower limb was 2.281.The diameter of
popliteal vein and
femoral vein in affected side
limb was respectively (8.8±1.2) mm and (12.9±2.7) mm,which was significantly larger than those in normal side
limb[ (5.9 ±1.5) mm and (9.2±2.1 ) mm](P< 0.05).ConclusionHigh frequency two-dimensional and
color Doppler ultrasonography has high precision in the
diagnosis of
lower limb deep venous thrombosis and with certain sensibility and
specificity.
