Practical role for ultrasound in diagnosis of deep venous thrombosis of lower extremities.
The Doppler Ultrasonic Velocity Detector has been shown to be of significant value in the evaluation of patients with suspected deep venous thrombosis. Our experience in 121 patients demonstrates a false-negative rate of 10% for "minimal" thrombophlebitis and 3.2% for ileofemoral thrombosis when the Doppler was used as a diagnostic aid. Since ileofemoral thrombosis represents the greatest threat to the patient in terms of pulmonary embolism, this appears to be a sensitive and specific technic for the detection of ileofemoral thrombosis.
