Patients with high-risk or intermediate-high-risk PE may require immediate reperfusion therapies, including percutaneous pulmonary thrombectomy. However, this procedure can be associated with significant hemodynamic and respiratory instability, potentially leading to shock, cardiac arrest, or the need for advanced support such as mechanical ventilation or extracorporeal membrane oxygenation (ECMO).\n\nThe mechanisms, timing, and causes of intraprocedural hemodynamic and respiratory deterioration during pulmonary thrombectomy are not well established. Factors such as catheter manipulation within the pulmonary arteries, increased pulmonary pressures, and the effects of anesthesia and mechanical ventilation may contribute to clinical instability. In addition, biomarkers such as NT-proBNP may reflect right ventricular strain and could help predict the risk of instability during the procedure.\n\nThe aim of this prospective observational study is to determine the incidence, causes, and timing of hemodynamic and\u002For respiratory instability during percutaneous pulmonary thrombectomy in patients with high-risk or intermediate-high-risk PE. The study will also compare the occurrence of instability between different thrombectomy devices (FlowTriever® and Indigo® systems) and evaluate the prognostic role of baseline NT-proBNP levels. Secondary objectives include the assessment of in-hospital and 30-day mortality and their underlying causes.\n\nThis study will include adult patients undergoing percutaneous pulmonary thrombectomy as part of routine clinical care. The results of this study may help improve risk stratification, guide procedural planning, and optimize the management of patients undergoing pulmonary thrombectomy, ultimately aiming to reduce morbidity and mortality.",[71],"Pulmonary Embolism Acute",[73,74,75,76,77,78,79],"Pulmonary Embolism","Percutaneous Pulmonary Thrombectomy","Catheter-Directed Thrombectomy","Hemodynamic Instability","Respiratory Instability","Shock","NT-proBNP","NOT_YET_RECRUITING","2026-04-28",{"date":83,"type":84},"2026-05-04","ACTUAL",{"date":86,"type":67},"2026-04-10",{"date":88,"type":67},"2030-05-10",{"name":5,"class":6},1]
