Abstract:
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 2.28:1.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.
