Answer

Answer

The OptEase filter is similar in design to the permanent TrapEase filter. It is cut from a single tube of nitinol, with a 6-sided, conical shape and dual-level clot-trapping capability. Although the OptEase filter can be deployed via either a femoral or jugular approach, the provision of a hook on the caudal end and unidirectional anchoring barbs to prevent cephalad migration allow retrievability from the femoral approach, which is unique to this design.

In 2002, this filter was approved by the FDA for retrieval times of up to 23 days. The introducer system has a profile similar to the TrapEase filter; the retrieval system is 10F.

Kim et al reported 11 cases (4.2%) of new PE and 1 case (0.4%) of IVC thrombosis in 260 OptEase filters placed. [87] Keller et al reported on removal of 58 of 80 OptEase filters placed, [88] in which 5 patients required additional access during retrieval, because the hooklet could not be engaged. The IVC thrombosis rate in their series was 3%. [88] No IVC thrombosis was seen in 27 patients reported by Oliva et al, [89] or in 94 patients reported by Rosenthal et al. [90] However, Corriere et al reported 3 (12.5%) cases of IVC thrombosis in 24 patients with retrievable filters; all 3 were OptEase filters. [91]
