Venous thromboembolism (VTE)
that is, deep venous thrombosis
(DVT) and pulmonary embolism (PE)
are common complications after major
hip or knee surgery. Without thromboprophylaxis, the incidence of DVT
in patients undergoing major orthopaedic surgery is more than 50%, and
fatal PE is reported to occur in 1-6% of these
patients.1 These data are based on investigations in which
predominantly osteoarthritis (OA) patients were studied. Only a few
(small) studies were performed in rheumatoid arthritis (RA) patients: Abernethy reports an incidence of DVT of more than 70% and overall incidence of PE of approximately 2% in RA patients who have undergone a knee arthroplasty,2 and Kelly reports, in his
review,3 an incidence of fatal PE of approximately 1% in
RA patients undergoing total hip replacement and not receiving
thromboprophylaxis (table 1). The risk of developing DVT seems to be
similar for RA patients undergoing total hip replacement and those
undergoing
