Pulmonary embolism (PE) still has a high associated mortality. Anticoagulation should be continued until the benefit of preventing recurrent PE is outweighed by the risks of bleeding. Furthermore, D-dimer values and residual clot burden may predict recurrent thromboembolic events in patients that have completed anticoagulation therapy. The authors describe the case of a 69-year-old female who suffered multiple recurrent PE on aspirin, her medical history included idiopathic PE, and she had been on anticoagulant for a considerable time before switching to aspirin. It is important the possibility of recurrent PE be borne in mind to prevent secondary prevention, and that other treatment options be considered in cases of recurrent PE.
