We all know the type: the person at the party who cannot bring themselves to leave. Whether they just like the sound of their own voice or fear of facing what is at home is just too much, knowing when your time is up is critical. (Watch this segue.) And the same goes for IVC filters.
After surgery, the risk of blood clots forming goes up. If one of those clots makes it into the lungs, it can be bad. Like, pulmonary embolism-bad. So, surgeons can place a metal cage or filter in a vein, called the inferior vena cava, to trap blood clots to prevent them from reaching the lungs.
These filters have several metal spines, and in a pinch, can also be used to catch bass and stripers. (This statement has not been evaluated by the FDA.) What has been stated by the FDA is that leaving an IVC filter in too long can be dangerous.
What does this mean to you:
It can sometimes be as important to know when to stop using a particular medical device as it can be to know when to start.
