Screening for lower extremity deep venous thrombosis

摘要: Noninvasive screening of the lower extremities for deep vein thrombosis was performed bilaterally on 1,118 patients. Impedance plethysmography alone used in 868. Venography 135 revealed an accuracy 88%, with a false-negative rate 5.3% and false-positive 18.6%. A combined ultrasonic Doppler modified impedance technic 250 forty 95%, 10% no undetected thrombi. The technic, emphasizing more accurate modality three anatomic areas, has proven sensitive, specific, reliable as test venous thrombosis.
