Most experts agree with placing an inferior vena caval (IVC) filters in patients with acute proximal DVT and an absolute contraindication to anticoagulation. If the contraindication to anticoagulation is temporary (eg, perisurgical patients), placement of a retrievable IVC filter should be considered so that the device can be removed once anticoagulation has been started and has been shown to be tolerated.
Complications of IVC filters include local thrombosis, tilting, migration, and inability to retrieve the device.
