Endovascular Treatment of Massive and Submassive Pulmonary Embolism

Massive and submassive pulmonary embolism constitutes the high- and intermediate-risk categories of pulmonary embolism. Both are associated with higher rates of mortality and morbidity and may benefit from more aggressive management than from standard anticoagulation alone. Endovascular treatment is a promising treatment modality that may offer added benefit at low additional risk.
