The Pulmonary Embolism Prevention Trial (PEP) was a randomized clinical trial designed to test whether aspirin reduces in-hospital morbidity due to venous thromboembolism in high-risk patients undergoing surgery for hip fracture and elective hip or knee arthroplasty. Combining clinical probability, perfusion and ventilation lung scans, and lower extremity venous ultrasonography also allows clinicians to withhold anticoagulants safely. Prevention of Fatal Pulmonary Embolism in the Hospital. One of the major limitations to successful outcomes with catheter directed treatment is the need for local expertise to perform the procedure.
