“…The many instances of low levels of D-dimer in association with a positive venogram may be a function of the absence of active clotting at the time of the plasma sampling, particularly if a large proportion of thrombosis occurred on the day of the operation (8). The incidence of preoperative thrombosis is very low in this type of population (8,9). A further factor might be that the method was used in the manner of a screening test rather than to investigate clinically suspected thrombosis.…”

SummaryPlasma levels of D-dimer have been found useful as a marker of deep venous thrombosis in those patients in whom thrombosis is suspected, but their usefulness in postoperative screening is less clear. We have investigated the relationship of D-dimer to deep venous thrombosis in 90 patients after total hip and knee arthroplasty. From the first postoperative day the D-dimer levels were found to be highly significantly raised in patients with deep venous thrombosis. A combined result over the first six postoperative days in excess of 1200ng/ml correlated with thrombosis with a specificity of 100%, sensitivity of 45%, positive predictive value of 60%, and negative predictive value of 100%. However, individual estimations were not discriminatory.
