C-35 | Predictors of Early vs Late Catheter Directed Embolectomy Intervention for Pulmonary Embolism

Catheter Directed Embolectomy (CDE) is a growing modality in the treatment of pulmonary embolism (PE). We aim to study predictors early (within 48 hours) comparison late (> 48hours) CDE intervention. The National Inpatient Sample database was queried from years 2016-2019 obtain our sample PE admissions using appropriate ICD-10-CM codes primary diagnosis field. Those with concurrent ischemic stroke, limb ischemia, or coronary revascularization same admission were excluded and cohort divided into intervention CDE. Chi-square t-test analysis used compare characteristics both groups multivariate regression derive through odds ratio (OR). 6,430 hospitalizations received CDE, which 5,165 underwent 1,265 Patients who got interventions older (62.1 ± 14.6 vs 60.6 15.6, p<0.01) had lower Charlson comorbidity index score (1.8 2.1 2.4, p<0.01). Furthermore, patients more likely have needed vasopressor use (OR: 0.35, p<0.01), ECMO 0.10, peripheral thrombolysis 0.72, mechanical ventilation 0.62, than group. In this study, ECMO, use, thrombectomy PE. More data define criteria for optimum timing critical patient population.
