Forty patients with a clinical suspicion of deep venous thrombosis (DVT) of the lower limb were submitted to real-time ultrasound examination prior to venography. The ultrasound diagnosis DVT was made at the presence of at least one of two criteria: intraluminal thrombus and absence of vein compressibility. One ultrasound study was inconclusive. In 14 patients the ultrasound diagnosis was DVT, and in 12 of these this was confirmed at phlebography. There were thus two false positive ultrasonic diagnoses, PV pos = 0.86. In 25 patients, the diagnosis was no DVT on both ultrasound study and venography, PV neg = 1.00. Ultrasound examination is recommended as the first choice of diagnostic imaging in patients with suspected DVT.
