BACKGROUND: This study retrospectively reviewed results of simultaneous (SIM) inferior vena cava (IVC) filter and separate (SEP) IVC filter placement with open pulmonary thromboembolectomy (PTE) in pulmonary embolism and its clinical outcomes. MATERIALS AND METHODS: From November 2006 to May 2014, 23 patients (14 females and 9 males; median age 58 years; range, 21-88 years) underwent emergent PTE for submassive (12) or massive (11) pulmonary embolism (PE). All had a preoperative computed tomography (CT) scan and echocardiography consistent with right ventricular (RV) strain. Mean cardiopulmonary bypass times and temperatures; chest tube outputs; length of stay; perioperative complications; and survival were compared between groups. RESULTS: There were 13 patients in the SIM group and 10 in the SEP group. PE consisted of 14 acute (60.9%) and nine acute on chronic (39.1%). There were seven deaths (30.4%). Median follow up was 44 days (range, 2-2204 days). Follow up was 81% complete in surviving patients. Actuarial survival at one and three years was 83% for the SIM group and 43% for the SEP group, respectively. There were no differences in cardiopulmonary bypass (CPB) times and temperatures, chest tube outputs, or length of stay between groups. Using multivariable logistic regression, we found SIM was associated with increased survival (p=0.09). Further analysis showed patients >55 years in the SEP group were at significantly higher risk of death (hazard ratio [HR]=7.1:1; 95% confidence interval [CI]: 1.55, 32.5, p=0.011). CONCLUSION: IVC filter placement can be performed simultaneously and safely at PTE. Age >55 years and PTE with IVC filter placed separately were at significantly higher risk of death. A larger cohort is needed to evaluate efficacy of simultaneous IVC filter placement and PTE.
