RT Journal Article SR Electronic T1 Preoperative antithrombin III activities and lipoprotein concentrations as predictors of venous thrombosis in patients with fracture of neck of femur. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 570 OP 573 DO 10.1136/jcp.36.5.570 VO 36 IS 5 A1 J H Winter A1 A Fenech A1 B Bennett A1 A S Douglas YR 1983 UL http://jcp.bmj.com/content/36/5/570.abstract AB The presence or absence of venous thrombosis was determined by the technique of autologous 111indium-labelled platelets in 64 patients following reduction and fixation of fractures of the neck of femur. Venous thrombosis was found in 41 (64%) of these patients. Compared to the thrombosis-negative group, the thrombosis-positive group had a significantly lower mean serum antithrombin, and higher mean antithrombin consumption during clotting in the immediate preoperative period. No significant differences were seen between the two groups in plasma ATIII activities, fibrinogen, alpha-2-macroglobulin, serum lipoproteins or age. Significant correlations were seen between ATIII activities and lipoprotein fractions; these are discussed.
