Preliminary experience with option inferior vena cava filter

Objectives: To evaluate the safety and efficacy of Option inferior vena cava (IVC) filter during placement and short-term follow-up. Methods: A total of 165 patients (mean age: 60-years) who received Option IVC filter from June 2009 to July 2011 were included. In all, 42 patients presented with deep vein thrombosis (DVT), 26 with pulmonary embolism (PE), and 17 with both. All outcomes were examined until April 30, 2012. Results: The filters were successfully deployed in 161patients. During follow-up (mean, 9.5±0.68months), 10 patients were diagnosed with post-filter PE and 13 patients with DVT. There were no instances of fatal PE. Follow-up abdominal computed tomography was available in 60 patients and demonstrated filter-related problems in 8 patients (2: penetration of filter legs, 5: asymptomatic nonocclusive thrombus, and 1: caval occlusion). There were no instances of filter migration or fracture. In total, 27 filters were successfully retrieved after a mean of 5.27 ± 0.76 months. Conclusion: The Option filter was effective and safe during implantation and short-term follow-up and associated with high technical success at retrieval.
