You have been scheduled to have an inferior vena cava (IVC) filter placed at UW Health University Hospital.
Go to this location at University Hospital:
G3/3 Radiology Waiting Area
F6/3 Heart and Vascular Procedure Center
You should plan to stay for 4 to 6 hours.
What is an IVC Filter?
An inferior vena cava (IVC) filter is a device used to trap blood clots before they reach the heart and lungs. The inferior vena cava is a large vein that carries blood from the lower body to the heart and lungs. The filter is used to trap blood clots before they reach the heart and lungs. IVC filters may or may not be left in for a brief amount of time.
Why do I need this filter?
This filter is used because you are at risk of blood clots traveling to the heart and lungs.
What is some of the risks with IVC filter placement?
Your doctor will review your risks with the IVC filter placement. Please write any questions to discuss with your doctor when you meet to discuss procedure.
How Is It Inserted?
The IVC filter is inserted through a small tube (catheter) placed in your groin or your neck vein. The small tube is advanced to the site where the IVC filter will be placed. The IVC filter is released once in place. The small tube is removed, and pressure will be held at the insertion site to reduce bleeding.
NOTE: Be sure to tell your doctor or nurse if you are allergic to x-ray dye (contrast). This may require pre-treatment medication.
A nurse will call you a few days before to give you instructions and information.
Do not eat or drink anything after midnight or earlier if so told. If your procedure is scheduled for late morning or later, you will be told if you can have a liquid breakfast.
Bring a list of your medicines including inhalers, over the counter medicines and supplements.
If you use a CPAP or BiPAP machine for breathing, bring it with you. Bring the hoses and mask.
You must have a responsible adult drive you home and stay with you for at least 6 hours after getting home.
The Day of the Procedure
Take your medicine as instructed. You may have been asked not to take some medicines before the procedure.
Please arrive at the time you were told.
You will change into a gown (without snaps). You may want to wear anti-slip socks; the room is kept very cool.
Remove watches, earrings, necklaces, or medic alert bracelets.
Glasses and hearing aids can be worn.
Remove contact lenses. Bring your solution and case for storage.
In the Lab Room
You will be helped onto the table.
You will lie flat so that the x-ray machine can rotate around the upper part of your body.
If you have back problems, tell the staff so that they can help you find a more comfortable position.
Patches will be placed on your upper body. These patches are hooked to machines that show your heartbeat.
Your doctor will tell you which location will be used for the procedure. This area will be cleaned.
You will be covered from your head to feet with a sterile sheet. Once the sheet is placed over you, keep your arms at your side. If you need to move your arms, ask the nurse to guide you.
Your doctor will inject a small amount of medicine into the site. It will burn a little, it will quickly numb the area. This will prevent you from feeling pain at this site. You will feel pressure, pulling, and tugging at the site where the tube is inserted.
You will be given medicine for pain and to make you sleepy. You will be sleepy but able to talk with staff.
After numbing the site, the doctor will insert a small needle and small tube (called a catheter) in the vein. An IVC filter or removal catheter is passed through the tube up to the location for release (placement) or hook (removal).
During the procedure, your doctor may ask you to take a deep breath, hold your breath, or breathe normally.
For deep breaths, breathe in slowly, as if sucking through a straw. No short, jerky breaths. Hold the breath until told to breathe normally. A deep breath helps us see your heart better. When asked to breathe normally again, gently let your breath out so that the small tubes remain in place.
After the Procedure
The doctor will remove the small tube. They will hold pressure on the site to stop any bleeding. You will return to a room to recover. Your nurse will tell you when you can get out of bed after you return to your room.
Do not drive
Do not make important decisions
No dangerous activities
Do not drink alcohol until the next day.
Remove the bandage after 24 hours. Shower by letting soap and water flow over the site.

Check daily for signs of infection:
Warm or hot at the site
Foul smelling pus
Fever of 100° F or higher for 2 readings taken 4 hours apart
Your doctor will let you know if your device will be removed and when.
How Is It Removed?
The IVC filter is removed through a small tube (catheter) placed in your neck vein. The small tube is advanced to the site where the IVC filter is located. The IVC filter is “hooked” and removed. The small tube is removed, and pressure will be held at the insertion site to reduce bleeding.
