Not all retrievable IVC filters should be removed if the risk of clots traveling to the lung persists and if blood thinners continue to be unusable. Your referring physician will determine if blood thinners are still necessary. However, it does not address the cause of the DVT. Removing an IVC filter eliminates any long term risks of filter fracture or recurrent DVT. This should be assessed by a physician or the interventional radiologist who inserted the IVC filter sometime after placement, ideally less than six months after insertion. This removal may be performed when the risk of clot travelling to the lung has passed. Newer filters, called optionally retrievable filters, may be left in place permanently or have the option to potentially be removed from the blood vessel later. Until recently, IVC filters were available only as permanently implanted devices. An IVC filter is a small metal device that traps large clot fragments and prevents them from traveling through the vena cava vein to the heart and lungs, where they could cause severe complications such as pain, difficulty breathing, shortness of breath or even death. In an inferior vena cava filter placement procedure, interventional radiologists use image guidance to place a filter in the inferior vena cava (IVC), the large vein in the abdomen that returns blood from the lower half of the body to the heart.īlood clots that develop in the veins of the leg or pelvis, a condition called deep vein thrombosis (DVT), occasionally break up and large pieces of the clot can travel to the lungs.

Your doctor will instruct you on how to prepare for the procedure. They are used in patients who don't respond to or cannot be given conventional medical therapy such as blood thinners. IVC filters help reduce the risk of pulmonary embolism by trapping large clots and preventing them from reaching the heart and lungs. Blood clots in the veins of the legs and pelvis can occasionally travel to the lungs where they may cause a pulmonary embolism or blockage. During Inferior Vena Cava (IVC) filter placement, a filtering device is placed within the IVC, a large vein in the abdomen that returns blood from the lower half of the body to the heart. ![]()
