Free-floating iliofemoral or IVC thrombus has been associated with a 27-60% rate of PE. Therefore, it is considered an indication for IVC filter placement. However, results have not been consistent. For example, Pacouret et al did not find a higher risk for PE in patients with free-floating proximal DVT. [98]
