Inferior Vena Cava Filter Insertion
Insertion of an inferior vena cava (IVC) filter is a procedure in which a filter is placed into the larg e vein in your abdomen that carries blood from the lower part of your body to your heart (inferior vena cava). This filter helps to prevent blood clots in the leg s or pelvis from traveling to your lung s, which can be very dang erous.
The filter is a small, metal device that is shaped like the spokes of an umbrella. The filter is inserted throug h a pathway that is created in the neck or g roin. Filters are inserted when blood thinners (anticoagulants) cannot be used to prevent blood clots from forming . You may need filters rather than anticoag ulants because you have:
- Severe platelet problems or shortages.
- Recent or current major bleeding that cannot be treated.
- Bleeding associated with anticoagulants.
- Recurrence of blood clots while taking anticoagulants.
- A need for surgery in the near future.
- Bleeding in your head.
- Multiple broken bones.
Tell a health care provider about:
Any allerg ies you have, including iodine.
- All medicines you are taking , including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
- Any blood disorders you have.
- Any problems you or family members have had with anesthetic medicines.
- Any medical conditions you have.
- Any surgeries you have had.
- Whether you are prenant or may be pregnant.
What are the risks?
Generally, this is a safe procedure. However, problems may occur, including :
- The filter blocking the inferior venacava. This can cause leg swelling .
- The filter eventually failing and not working properly.
- The filter moving and traveling to the heart or lung s.
- Damage to the vein. This is rare.
- Bleeding .
- Allergic reactions to medicines or dyes.
- Damage to other structures or org ans.
- A pool of blood (hematoma) around the site where a flexible tube is put into a large vein (catheter insertion site).
