Outcomes of Mechanical Thrombectomy Compared With Systemic Thrombolysis in Pulmonary Embolism: A Comprehensive Evaluation From the National Inpatient Sample Database.

In this study, we utilized the National Inpatient Sample database to study the in-hospital outcomes of pulmonary embolism patients who underwent mechanical thrombectomy compared to those who underwent systemic thrombolysis. We found that the patients who were diagnosed with pulmonary embolism and underwent mechanical thrombectomy had significantly lower mortality compared to those who were treated using systemic thrombolysis. This study was the first of its kind, utilizing the national inpatient sample database for evaluation of mechanical thrombectomy in comparison with the standard of care. These result would direct further randomized controlled trials for better evaluation of the utilization of mechanical thrombectomy in the correct clinical context. Furthermore, our study demonstrated comparable peri-operative complications between the mechanical thrombectomy group and the systemic thrombolysis group. These results would direct clinicians to consider mechanical thrombectomy if clinically indicated given the promising results.
