BACKGROUND

The purpose of this study was to retrospectively assess the retrieval characteristics and rate of filter-related complications associated with use of the Celect Platinum (Cook Medical, Bloomington, Ind) inferior vena cava filter (IVCF).

METHODS

A single-center, retrospective review was conducted to identify patients who received a Celect Platinum IVCF between June 2013 and February 2016. The patients' charts and imaging records (computed tomography [CT] and cavography) associated with filter placement, follow-up, and filter retrieval procedures were assessed for attempted and successful retrieval rates and filter-related complications.

RESULTS

During the review period, 562 Celect Platinum filters were placed in 556 patients. Outcome and evaluable imaging data (CT and cavography) were available from 335 patients, with median CT follow-up time of 45 days (average, 126 days) and median cavography follow-up time of 90 days (average, 102 days). IVCF leg perforation of the inferior vena cava wall >3 mm was identified in 65 cases (19.4%) on follow-up imaging (64 cases). In addition, filter tilt >15 degrees was identified in 4 filters (1.2%), filter migration >2 cm in 1 filter (0.3%), and occlusive filter or inferior vena cava or iliac vein thrombus in 11 filters; no filter fracture was observed. One case of breakthrough pulmonary embolism and two additional indeterminate cases were identified on follow-up CT pulmonary angiography (2.6%-7.7%). Retrieval was successful in 155 of 155 patients (median indwell time, 90 days; range, 1-445 days); an advanced retrieval technique was used in 11 retrievals.

CONCLUSIONS

The outcomes for the Celect Platinum filter were comparable to those previously reported for the first-generation Celect filter in all categories assessed.
