What is a vena cava filter?

A vena cava filter may help prevent blood clots from travelling to the lungs, where they may block blood flow.

Your doctor removes the filter using a thin, flexible tube called a catheter. This goes into your vein. A removable filter has a small hook on it. The doctor can use the hook to help pull the filter out of the vein.

A filter may be taken out because it can cause problems if you have one for a long time.

You may go home the same day after the procedure. You may be able to go back to work or your normal routine in a day or two.

How do you prepare for the procedure?

Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.

Preparing for the procedure

• Be sure you have someone to take you home.
• 
  Talk to your doctor when you have questions about what procedure is planned, along with the risks, benefits, and other options.
• Tell your doctor ALL the medicines and natural health products you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
• Make sure your doctor and the hospital have a copy of your advance care plan. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.

What happens on the day of the procedure?

• 
  Follow the instructions exactly about when to stop eating and drinking. If you don't, your procedure may be cancelled. If your doctor told you to take your medicines on the day of the procedure, take them with only a sip of water.
• Follow your doctor's instructions about when to bathe or shower before your procedure. Do not apply lotions, perfumes, deodorants, or nail polish.
• Take off all jewellery and piercings. And take out contact lenses, if you wear them.

At the hospital

• 
  Bring a picture ID and your Alberta Health Care Insurance Plan card.
• You will be kept comfortable and safe by your healthcare team. The area being worked on will be numb.
• After the procedure, pressure will be applied to the area where the catheter was put in your blood vessel. Then the area may be covered with a bandage or a compression device. This will prevent bleeding.
• Nurses will check your heart rate and blood pressure. The nurse will also check the catheter site for bleeding.
• You may have a bruise or a small lump where the catheter was put in your blood vessel. This is normal and will go away.
