What Is an IVC Filter?
An IVC filter is a small device placed in a large vein (inferior vena cava) to stop blood clots from reaching the lungs. It acts like a tiny net inside your body.
Why Is It Used?
You may need an IVC filter if:
You have blood clots (DVT)
You are at risk of a lung clot (pulmonary embolism)
You cannot take blood thinners
How Is It Placed?
A small tube is inserted through the neck or groin
The filter is guided into the vein using imaging
The procedure takes about 30–60 minutes
Most patients go home the same day
