Abstract

Objectives: The aim of this study was to investigate the contemporary trends and comparative effectiveness of adjunctive inferior vena cava filter (IVCF) placement in patients undergoing catheter-directed thrombolysis (CDT) for treatment of proximal lower extremity or caval deep vein thrombosis. Background: CDT is being increasingly used in the management of proximal deep vein thrombosis. Although a significant number of patients treated with CDT undergo adjunctive IVCF placement, the benefit of this practice remains unknown. Methods: The National Inpatient Sample database was used to identify all patients with proximal or caval deep vein thrombosis who underwent CDT (with and without adjunctive IVCF placement) in the United States between January 2005 and December 2013. A propensity score–matching algorithm was then used to derive 2 matched groups of patients (IVCF and no IVCF) for comparative outcomes (mortality and major and minor bleeding) and resource use analysis. Results: Of the 7,119 patients treated with CDT, 2,421 (34%) received IVCFs. There was no significant difference in in-hospital mortality (0.7% vs 1.0%; p = 0.20), procedure-related hemorrhage (1.4% vs. 1.0%; p = 0.23), or intracranial hemorrhage (0.7% vs. 0.6%; p = 0.70) between the IVCF (n = 2,259) and no-IVCF (n = 2,259) groups, respectively. Patients undergoing IVCF placement had higher rates of hematoma (3.4% vs 2.1%; p = 0.009), higher in-hospital charges ($104,049 ± 75,572 vs. $92,881 ± 80,194; p < 0.001) and increased length of stay (7.3 ± 5.6 days vs. 6.9 ± 6.9 days; p = 0.046) compared with the no-IVCF group. Conclusions: This nationwide observational study suggests that one-third of all patients undergoing CDT receive IVCFs. IVCF use was not associated with a decrease in in-hospital mortality but was associated with higher inpatient charges and longer length of stay.
