Question:
What is the procedure to prevent pulmonary embolism?

My surgeon said he will insert a screen to prevent pulmonary embolism because I have a hx. of DVT (blood clots). Where does the screen get placed? Does anyone else have experience with this procedure?    — Aurele K. (posted on March 26, 2000)

Aurele, the screen is called a Greenfield Filter and is placed in a large vein in your abdomen, called the inferior vena cava. It looks like a little umbrella without the outer covering. Blood clots travelling through attach to it rather than floating to your heart, lungs or brain. It can be inserted through a vein in your groin or a vein in your neck, depending on your Dr.'s choice. It's not a difficult or painful procedure and is done with only a very small risk of complication. For people who have had problems with blood clots or are anticipated to have problems postop it is a life saver. Wishing you the best with your recovery, Sandy RN

I had a Birdcage filter...same idea...slightly different looking. Inserted after I had several large embolisms to prevent further damage or future such incidents.

I'm just adding to what has been said before. You legs have enzymes that dissolve blood clots naturally. The purpose of the device (screen, birdcage, umbrella, etc.) is to keep the clot in the lower extremity, which prevents it from getting to your heart, lung or brain and keeps it where the enzymes can dissolve the clot. My father had this procedure over 7 years ago and it has worked wonderfully.
