There are specific measures that can lower the risk of post-operative DVT, and pulmonary embolism as:

A study by Valle et al. followed 989 patients who underwent a total hip arthroplasty. Those patients received a single dose of unfractionated heparin intraoperatively, and additional treatment with aspirin in 87% of patients, and warfarin in 13% of patients. In those patients asymptomatic DVT occurs in 7.1% of patients, while symptomatic DVT occurs in 0.88% of patients.
