Explain an ivc filter placement?

IVC filter. An ivc filter is a small metal device shaped like an umbrella without the fabric. It is placed in patients who are at risk for pulmonary embolism, but who cannot tolerate or fail treatment with blood thinners. It is placed through a catheter via the jugular vein (in the neck) or the femoral vein (in the groin) .
Simple. I describe it to patients as an umbrella frame with no fabric. It can be placed from the neck or groin vein. There are several position the device can sit in the inferior vena cava but usually the apex of the device is at or near the inflow of the kidney veins. It is positioned through a small sheath under xray guidance. The feet of the device contact the vessel wall holding it in place.
Device catches clots. IVC = inferior vena cava, main vein moves blood from lower body to heart. Treatment for clots in major veins of legs (DVT) is blood thinners, which prevent clot going to lungs/heart. A few people can't get blood thinners, so filter (little wire cage) put in IVC thru little needle puncture to catch clots before they get to heart/lungs. Works well, but has side effects; use only if really needed.
