Evidence-based management of pulmonary embolism in the emergency department

Patients with pulmonary emboli present both diagnostic and therapeutic challenges to the emergency clinician, because initial symptoms can be variable and overlap with other medical conditions. This issue reviews treatment options for patients with pulmonary emboli based on risk stratification scores of low, intermediate-low, intermediate-high, and high risk classifications. The evidence on laboratory testing and imaging is presented, as well as treatment strategies that include anticoagulation, thrombolytics, and mechanical or surgical thrombectomy. Management decisions regarding pregnancy and COVID-19 are discussed, as well as considerations for outpatient treatment of low-risk patients.
