Cohort Study on Treatment Comes of Catheter-based Therapy in Patients With Acute Pulmonary Embolism in Hong Kong

This retrospective cohort study (Hong Kong PECT Registry) compares treatment outcomes between different percutaneous catheter-based therapies in patients with acute pulmonary embolism (PE). PE is a critical condition with potential for rapid deterioration and mortality before treatment. While availability of catheter-based therapy contributed to the declining mortality rates of PE, selecting the appropriate intervention remains key. There are primarily two modes of therapies available: Catheter-directed thrombolysis and Aspiration thrombectomy (e.g., Penumbra, Flowtriever, AlphaVac) Given limited direct comparisons between these methods, the study will evaluate their efficacy, safety, and clinical outcomes of these treatment strategies in acute PE patients.
