[Diagnosis of deep venous thrombosis of the lower limb by Doppler ultrasound technique].

In this study, eighty limbs (71 patients) with clinically suspected deep venous thrombosis (DVT) were investigated by both venography and Doppler ultrasonography. Diagnosis was confirmed by venography in 67 limbs and Doppler ultrasonography was positive in 66 of them with the Doppler sensitivity of 98%. In the remaining 13 limbs clinically suspected to have DVT, neither venography nor Doppler ultrasonography found any abnormality in the venous system of the lower limbs.
