Abstract
Filter position with respect to renal vein inflow influences filter trapping hemodynamics. Placement of the TrapEase filter in a suprarenal location may be thrombogenic, with redundant areas of stagnant/recirculating flow and low shear stress along the caval wall caused by the upstream trapping position and the naturally occurring region of stagnant flow from the renal veins. Infrarenal vein placement of IVC filters in a near-juxtarenal position with the downstream cone near the renal vein inflow likely confers increased levels of mechanical lysis of trapped thrombi from increased shear stress from renal vein inflow.
