Purpose: To evaluate causes of failed optional inferior vena cava filter (IVCF) retrievals.
Methods: Single-center retrospective study.
Results: IVCF retrievals were attempted in 26/211 (12%) patients at a mean 42.9 days. There were 9 failures (all OptEase) due to: inability to snare the hook (n=5), noncollapsible IVCF (n=3), and unusual procedural pain (n=1). Median duration of retrieved IVCFs was 31 days compared to 53 days for failures (P<.05). IVCFs aligned with the IVC's cephalocaudal axis were retrieved in 13/16 cases, while misaligned IVCFs were retrieved 4/10 cases (P<.05).
Conclusion: Filter duration and misalignment were significantly associated with retrieval failures.
