title: OptEase and TrapEase vena cava filters: a single-center experience in 258 patients.
abstract: We aimed to evaluate the efficacy and safety of the OptEase and TrapEase (both from Cordis, Roden, Netherlands) vena cava filters in the prevention of pulmonary embolism (PE). Between May 2004 and December 2008, OptEase (permanent/retrievable; n = 228) or TrapEase (permanent; n = 30) vena cava filters were placed in 258 patients (160 female and 98 male; mean age 62 years [range 22 to 97]). Indications were as follows: prophylaxis for PE (n = 239), contraindication for anticoagulation in the presence of PE or DVT (n = 10), and development of PE or DVT despite anticoagulation (n = 9). Medical records were retrospectively reviewed for indications, clinical results, and procedure-related complications during placement and retrieval. Clinical PE did not develop in any of the patients. However, radiologic signs of segmental PE were seen in 6 of 66 patients with follow-up imaging data. Migration or fracture of the filter or cava perforation was not seen in any of the patients. Except for a single case of asymptomatic total cava thrombosis, no thrombotic occlusion was observed. One hundred forty-one patients were scheduled to undergo filter removal; however, 17 of them were not suitable for such based on venography evaluation. Removal was attempted in 124 patients and was successful in 115 of these (mean duration of retention 11 days [range 4 to 23]). Nine filters could not be removed. Permanent/retrievable vena cava filters are safe and effective devices for PE prophylaxis and for the management of venous thromboembolism by providing the option to be left in place.
