PURPOSE: To evaluate retrospectively the safety and retrievability of the Celect IVC filter.
MATERIALS AND METHODS: All patients undergoing Celect filter placement and retrieval during the period 2007-2012 were assessed for complications and retrievability.
RESULTS: Of 620 patients who underwent Celect filter placement, 120 presented for removal. The indwelling time in these patients was 158.1 days±103.0 (range, 2-518 d). There were 106 filters (88.3%) removed; 14 filters were left in situ for the following reasons: filter embedment (n=6), caval occlusion (n=3), retained thrombus (n=2), large floating thrombus in IVC (n=2), or tilt >15° (n=1). With filters in place, five patients developed new pulmonary embolism (PE), and two others presented with severe abdominal pain. The available 115 pairs of placement and removal cavagrams suggested limb penetration in 99 cases (86.1%), intracaval migration >2 cm in 5, secondary tilt >15° in 8, filter deformity in 10, retained thrombus within filters in 12, and IVC occlusion in 3. Among 38 available computed tomography (CT) scans, 9 scans (24%) showed asymptomatic limb penetration to the duodenum (n=6), aortic wall (n=2), or kidney (n=1). No filter fracture was found.
CONCLUSIONS: This study showed a high penetration rate for Celect IVC filters, including penetrations that were symptomatic or involved adjacent structures. Penetration appears to correlate with indwelling time, suggesting that the filter should be removed as soon as PE protection is no longer indicated. Although most of the filters were removed, 5.8% of retrievals were unsuccessful because of technical failure.
