AbstractDuplex ultrasonography of the deep venous system of the lower extremities is often utilized in the diagnostic evaluation of total hip and knee arthroplasty patients suspected of pulmonary embolism in an attempt to identify the embolic source. A retrospective review of 135 patients who were clinically suspected of pulmonary embolism after 71 total knee arthroplasties and 64 total hip arthroplasties was performed. Of the 35 patients diagnosed with pulmonary embolism, 2 (5.7%) had deep venous thrombosis identified by duplex ultrasonography. The routine use of this imaging modality is not an effective strategy for identifying clinically significant deep venous thrombosis that leads to pulmonary embolism. A negative duplex ultrasound result should not preclude an extensive evaluation for pulmonary thrombosis in symptomatic patients.
