Abstract No. 111 Retrospective review of complications and outcomes of 603 Option Elite inferior vena cava filter placements

To retrospectively identify the frequency of complications, removals, and clinical outcomes in patients in whom Option Elite inferior vena cava (IVC) filters were placed, and their associated clinical and procedural factors. The Radiology Information System for 7 hospitals was queried for accession numbers with reports containing the words “option” and “filter” between January 1, 2013, and April 19, 2019. The electronic medical record and imaging studies were reviewed for clinical information at the time of placement, follow-up clinical information, complications, and removal procedures. Patient charts were assessed until both their first clinical note and first imaging of the filter after June 1, 2019. 603 Option Elite IVC filters were evaluated. Of 192 filters with attempted removals, 189 were removed after a mean of 4.3 months. Mean follow-up for all filters left in place was 14.7 months. 211 patients died during follow-up, without filter-related mortality. Following placement, there were 19 (3.2%) patients with symptomatic pulmonary embolism (PE), 16 of which were low risk and 3 of which were submassive. 68 (11.3%) patients developed deep venous thrombosis including 14 that involved the IVC. There was one filter which migrated more than two centimeters, two that fractured, 17 that perforated the IVC wall, and 48 demonstrated associated clot, of which a majority (38) were deemed to be likely clot caught by the filter. The final abstract/paper will include additional analysis which are pending, including, if found, factors that are associated with higher or lower complication rates. Option Elite IVC filters are associated with a low rate of clinically significant complications, including a 3.2% rate of symptomatic PE with no massive PE identified.
