| The positive findings of deep vein thrombosis on duplex Doppler ultrasonography such as intraluminal clot,non-compressibility of the venous lumen and abnormal or absent Doppler shift signal are well known. However,relatively hypoechoic thrombus is not always seen in sonography, and the vein is frequently compressible inpartial thrombosis. In order to evaluate the most common and important findings of deep vein thrombosis, weanalysed the findings at duplex Doppler ultrasound in 19 patients and compared the results with those of contrastvenography in 11 patients. Duplex Doppler ultrasound examination of the common femoral and popliteal veins wasperformed for one extremity in 14 patients, and for both extremities in 5 (total 24 extremities). Contrastvenography was performed for one extremity in 7 patients, and for both sides in 4 (total 15 extremities).Thrombosis was seen in 45.8%, non-compressibiliy of lumen in 75%, absent or decreased Doppler signal from commonfemoral vein in 95.8%. Thrombosis was seen in 41.7%, non-compressibility of lumen in 70.8%, absent or decreasedDoppler shift signal from popliteal vein in 95.8%. We conclude that abnormal or absent Doppler shift signal is themost sensitive and important finding of the deep vein thrombosis. |
