Abstract

Impedance plethysmography (IPG) is a useful noninvasive detection of proximal segment thrombosis. Seven hundred patients treated with total hip arthroplasty were examined preoperatively and several times postoperatively using this technique. Twenty-one abnormal IPG results were obtained, and venography confirmed that 12 of these patients had proximal segment thrombi and five had evidence of calf thrombi. Four venograms were completely clear, demonstrating a false-positive rate of 1.3% (including calf thrombi). Six patients with normal IPG results had calf thrombi. All positive venograms indicating a thrombus in the proximal venous segment were indicated with a positive IPG result, giving a sensitivity of 100%. The standardization of the procedure involving constant leg elevation has assisted in the accuracy of this screening system.
