An Attempt at Predicting Postoperative Deep Vein Thrombosis by Preoperative Coagulation Studies in Patients Undergoing Total Hip Replacement

Abstract
Summary: 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.
