Retrievable IVC filters have been associated with reports of fracturing and migration. Most often, the fractured portions of the device migrate to the heart and lungs of its victim. However, fragments of IVC filters can also migrate to other organs. Once the metal fragments from a retrievable IVC filter have deposited in the heart, lungs or another organ, grave injury, bleeding, severe pain, further embolus and other complications can occur.
IVC filters are placed in the inferior vena cava of individuals who have deep vein thrombosis in their legs to prevent blood clots that break off from traveling to the heart, lungs and brain. There are two types of filters: permanent and retrievable (meaning the filter is removed once the risk of emboli resolves). While most IVC filters currently on the market are permanent, the retrievable models appear to be associated with the most complications.
