Pulmonary embolism (PE) results from embolization of venous thrombi in the branches of the pulmonary arteries. Although anticoagulation is usually the preferred method of treatment, patients with high-risk and/or intermediate/high-risk pulmonary embolism may benefit from immediate reperfusion therapy, such as mechanical catheter thrombectomy. During this procedure, there may be an increase in pulmonary pressures caused by the introduction of pulmonary catheters, which may trigger hemodynamic instability. In addition, anesthesia performed during percutaneous mechanical thrombectomy may precipitate hemodynamic and respiratory compromise due to hypoxia, hypercapnia and increased airway pressure. We will perform a retrospective, single-center study to determine the incidence and immediate causes of hemodynamic and/or respiratory deterioration, before, during and after (first 30 days) of percutaneous pulmonary thrombectomy, as well as the need for mechanical respiratory/circulatory support.
