INFERIOR VENA CAVA FILTER PLACEMENT
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. 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. IVC filters help reduce the risk of pulmonary embolism by trapping large clots and preventing them from reaching the heart and lungs. They are used in patients who don't respond to or cannot be given conventional medical therapy such as blood thinners.
INFERIOR VENA CAVA FILTER REMOVAL
The procedure to remove the IVC filter is very similar to the procedure used to place it. A small catheter-based wire loop (snare) is inserted into the large vein in the neck. A removable IVC filter contains a small hook at one end. With X-ray guidance, your doctor uses the snare to grasp the hook and withdraw the filter. If this is unsuccessful, advanced complex filter removal techniques can be used very effectively. These procedures are performed on an outpatient basis under sedation, with brief post-procedure observation and return to normal activities the next day.
