The US Food and Drug Administration (FDA) has recommended that clinicians remove retrievable inferior vena cava (IVC) filters as soon as the risk of blood clots has subsided.
IVC filters are cage-like devices that are inserted into the IVC to stop the blood clots from reaching the lungs.
The FDA said it has received 921 reports of adverse clinical outcomes of IVC filters, caused by filter fracture, filter detachment and perforation of IVC.
The regulator feels that extended use of retrievable IVC filters may be contributing to this problem.
Retrievable IVC filters are only used to provide short-term protection from blood clots.
