This information will prepare you for your inferior vena cava (IVC) filter placement by the Interventional Radiology Department at Memorial Sloan Kettering (MSK).
About the IVC Filter
The filter is a small device that will be placed in the large vein below the level of your heart, called the inferior vena cava (see Figure 1). The IVC filter will filter your blood to prevent a blood clot from traveling from your legs to your lungs. You need a filter either because you cannot receive medication to thin your blood (called anticoagulants), or because you need a filter in addition to blood thinners.
The filter is often placed before surgery by an interventional radiologist. It is usually placed in the IVC by going through a vein in your neck; however your doctor may place it by going through a vein in your groin. Going through a vein in your groin is not as common. Your doctor will position the filter in the vein using fluoroscopy (real-time x-rays).
The procedure will take about 30 minutes, however you should expect to be in the procedure room for about an hour. The doctor who placed the filter will see you in clinic usually 4 to 6 weeks after placement to evaluate when it is safe to be removed.Back to top
Before Your Procedure
You may need to stop taking some of your medications before your procedure. Talk with your doctor about which medications are safe for you to stop.
If you take medication that affects the way your blood clots, ask the doctor performing your procedure what to do. The doctor’s contact information is listed at the end of this resource. Some examples of these medications are:
inflammatory drugs (NSAIDs)
Whether he or she recommends you stop taking it will depend on the reason why you are taking these medications. Do not stop taking any of these medications without talking with the doctor who prescribed them for you.
Please review the information in the resource Common Medications Containing Aspirin and Other Nonsteroidal Anti-Inflammatory Drugs (NSAIDs). It includes important information about medications you’ll need to avoid before your procedure and what medications you can take instead.
If you take insulin or other medications for diabetes, you may need to change the dose before your procedure. Ask the doctor who prescribes your diabetes medication about what you should do the night before and the morning of your procedure.
If you take any diuretics (medications that make you urinate more often), you may need to stop taking them the day of your procedure. Some examples are furosemide (Lasix®) or hydrochlorothiazide. Speak with your doctor.
You must have someone 18 years or older take you home after your procedure. If you don’t have anyone, call one of the agencies below. They will provide someone to accompany you home, however there is usually a charge for this service and you will also need to provide your own transportation.

What to expect
Once you arrive, doctors, nurses, and other staff members will ask you to state and spell your name and date of birth many times. This is for your safety. People with the same or similar names may be having procedures on the same day.
If you don’t have an intravenous (IV) catheter, your nurse will put one in.
You will go to the recovery room after the procedure, and stay until you’re awake.
When you go home
- Leave the bandage on the insertion site for 24 hours.
- Do not shower for 24 hours.
- It is common for the incision site to feel sore. This pain should get better within a day or 2. You can take over-the-counter pain medication if you need it.
- Wearing a seatbelt may put pressure on your incisions. If so, you can put a small pillow or folded towel between the strap and your body.
- For the first few days, you should avoid certain activities such as exercises that involve forceful reaching or stretching.
- Watch for signs of infection at the insertion site, although infections are not common. Signs of infection include:
- A temperature of 100.4° F (38° C) or higher
- Foul-smelling drainage
- If you see any signs of infection, call Interventional Radiology at the numbers at the bottom of this resource.
- Once your incision is closed you can take tub baths and swim. This usually takes about a week.
- You can still have a magnetic resonance imaging (MRI) while you have an IVC filter, but it is important to tell the healthcare provider at the radiology facility each time to be safe.
- The filter will not set off metal detectors.
- The doctor who placed the filter will see you in clinic usually 4 to 6 weeks after placement to evaluate when it is safe to be removed.
