Pulmonary embolism (PE) is an important cause of morbidity and mortality and presents with significant diagnostic and therapeutic challenges. Clinical presentation ranges from mild, nonspecific symptoms to syncope, shock, and sudden death. Patients with hemodynamic instability and/ or signs of right ventricular dysfunction are at high risk for adverse outcomes and may benefit from aggressive therapy and support. Therapeutic anticoagulation is indicated in all patients in the absence of contraindications. Thrombolysis should be strongly considered in selected high- and intermediate-risk patients, either by systemic infusion or percutaneous catheter-directed therapy. Other therapeutic modalities, such as vena cava filters and surgical embolectomy, are options for patients who fail or cannot tolerate anticoagulation and/or thrombolysis. This article reviews the assessment and advanced management options for acute PE with focus on high- and intermediate-risk patients.
