IVC Filter Retrieval

What is an IVC filter?

IVC Filter

An IVC filter is a small metal device designed to prevent blood clots from traveling to the lungs. The filter is placed in the inferior vena cava (the large vein that takes blood back to the heart) typically just below the kidneys using a catheter type deployment device.

The procedure is performed by an interventional radiologist, interventional cardiologist or vascular surgeon. You will be awake during the procedure, but medication may be administered to help you relax. A local anesthetic is used to numb the insertion site. You will be monitored throughout the procedure.

A catheter is inserted through a small incision in your groin or neck into a large vein. The physician uses the catheter to guide the filter into place in the inferior vena cava under xray guidance. The vena cava is imaged and sized prior to filter deployment. The catheter is removed and a small bandage is placed over the insertion site.

If your procedure was performed using your groin, your activity will be briefly limited.

There are two general types of IVC filters ─ permanent and optionally retrievable. Your doctor may choose to use an optionally retrievable filter depending on your particular risk factors, length of time you are at risk for blood clots, and ability to take blood thinners. Placement of an IVC filter does not prevent new blood clots from forming. You may also be prescribed blood thinning medications to prevent future clots.

When should the IVC filter be removed?

It is <span>recommended</span> that the retrievable filter be removed when your doctor feels that the protection from DVT or VTE it provides is no longer necessary and it is safe for the filter to be removed.

How is the filter removed?

The IVC filter is removed via a similar process to the way in which it was placed. X-ray dye (contrast) will be injected around the filter to assure that the area beneath the filter is free of blood clots and that it is safe to proceed with removal. A catheter-based snare will be used to engage the hook at the end of the filter and the filter will then be enveloped by a removal sheath and removed from your body.
