Thromboembolic disease in patients undergoing total knee replacement
R McKenna, F Bachmann, SP Kaushal and JO Galante
In a prospective study fo the incidence of deep-vein thrombosis in thirty
patients undergoing total knee replacement, all patients had clinical
examinations and 125I fibrinogen scanning, while those suspected of having
deep venous thrombosis also had confirmatory venography. Sixteen (53 per
cent) of the thirty patients had thromboembolic disease; nine had thrombi
only in the limb operated on; four had bilateral deep venous thrombi; and
three had pulmonary embolism. In nine patients who took aspirin regularly
the incidence of thromboembolism was 11 per cent, while in the eight who
did not take aspirin or any other antiplatelet drug the incidence was 88
per cent, a difference which was highly significant (p = 0.003).
