You don't always need blood thinners with an IVC filter and whether or not you need blood thinners with the IVC filter also depends entirely you needed the IVC filter placed and your risk of bleeding.
Anticoagulation remains the primary, first-line treatment for blood clots.
If you can safely take anticoagulants, an IVC filter is generally unnecessary. However, if a filter is placed (e.g., because you had a life-threatening clot while already on blood thinners), you should remain on anticoagulation.
IVC filters are specifically designed as a mechanical alternative for people who have absolute contraindications to anticoagulants—such as active bleeding, recent major surgery, or a severe bleeding disorder.
In these cases, you do not use blood thinners with the filter.
The IVC filter's sole job is to catch large clots to prevent them from reaching your lungs.
Because IVC filters only catch clots and do not treat the underlying cause of the clot, the goal is to start or resume anticoagulation as soon as it is safe to do so.
If a temporary, retrievable filter was placed, it should be removed once your bleeding risk resolves and you can safely restart blood thinners.
Putting an IVC filter in takes between 30 minutes to 60 minutes and is a minimally invasive procedure that is done under local anesthesia and light sedation and most people go home the same day.
To prepare for the IVC filter procedure you will be given a local anesthetic to numb the insertion site, which is usually in your groin or neck along with a sedative.
The surgeon placing the IVC filter will use an X-ray or an ultrasound imaging for guidance and the surgeon will thread a small tube (catheter) through a minor incision into your vein.
The collapsed IVC filter ill then be navigated to the IVC and expanded, where it then anchors itself to the vessel walls to catch any blood clots.
After the catheter is removed, pressure is then applied to the site and you often need to lie flat for a couple of hours before going home.
You're awake for IVC filter placement as it's a minimally invasive outpatient procedure.
While you're awake for IVC filter placement, you will be given moderate sedation, also known as conscious sedation so you feel relaxed, sleepy and comfortable.
The care team will also use a local anesthetic to numb the exact spot of your neck or groin where they will be working.
The local numbing, blocks pain at the tiny cut in the skin and the IV sedative makes you feel very relaxed, although you might doze off lightly and general anesthesia may be used in rare cases if the moderate sedation is not safe for you.
What you may feel during the IVC filter placement is a sharp pinprick when the IV and numbing medicine go in and you may feel some mild pressure as the thin tube goes into your vein and you might even feel a warm feeling if the contrast dye moves through your body.
IVC filter placement is not a major surgery.
Instead IVC filter placement is actually a minimally invasive outpatient procedure.
IVC filter placement is done by an interventional radiologist or vascular surgeon making a tiny incision in your neck or your groin and then they guide the IVC filter into your inferior vena cava using a catheter as well as a real time X-ray imaging.
The procedure for IVC filter placement often takes between 20 minutes to 60 minutes and only uses local anesthesia or just mild sedation and it allows most people to go home the same day after the IVC filter placement.
You can often return to your normal activities within 1 to 2 days of the IVC filter placement surgery.
Recovery time after IVC filter placement is short.
You can usually go home the same day.
Expect to resume normal activities within 24 to 48 hours.
Avoid driving for 24 hours, and refrain from strenuous exercise and heavy lifting (over 10 pounds) for about 3 to 5 days.
Because IVC filter placement is minimally invasive, the recovery process is generally mild:
You will have a small incision in either your groin or your neck.
It is normal to experience some minor soreness, bruising, or discomfort for 24 to 48 hours.
This can usually be managed with over-the-counter pain medication.
Keep the bandage dry for the first 24 hours.
You should avoid taking baths or swimming for at least five days to prevent infection.
Your doctor will likely schedule a follow-up appointment in about 4 to 6 weeks to check on the placement and evaluate your overall recovery.
Many IVC filters are also designed to be temporary.
Your medical team will typically want to remove the IVC filter as soon as your risk for a pulmonary embolism decreases and you can safely resume blood thinner (anticoagulant) therapy.
The removal procedure for the IVC filter is similar to placement—usually done as a same-day, outpatient procedure.
