Preoperative levels of fibrinogen, factors V, VII, VIII and antithrombin III were
measured in 25 consecutive patients undergoing total hip replacement. Deep vein thrombosis
(D.V.T.) was detected by fibrinogen-uptake test in 60% of the patients. The preoperative
fibrinogen level was significantly higher (p < 0.05), and serum antithrombin III was
markedly lower (p ≦ 0.1) in patients with postoperative D.V.T. The quotient of fibrinogen
to serum antithrombin III was significantly higher (p < 0.01) in patients with D.V.T.
This quotient may serve as an additional parameter to other clinical and laboratory
tests in prediction of postoperative D.V.T. following hip surgery.
