Inferior Vena Cava Filter Insertion
What Is an IVC Filter Insertion?
An Inferior Vena Cava (IVC) filter is a small, metal device implanted into the largest vein in the body (the IVC) to prevent blood clots from traveling to the lungs. The procedure is typically done for patients who are at high risk of pulmonary embolism (PE) but cannot take blood thinners or need extra protection. The filter acts as a trap for clots, preventing them from reaching critical organs.
Why do I need this procedure?
Your doctor may recommend an IVC filter if you have:
Deep vein thrombosis (DVT) with a high risk of PE
A history of pulmonary embolism
Contraindications to anticoagulant therapy (e.g., bleeding disorders)
Recurring blood clots despite being on blood thinners
Recently undergone surgery or trauma and are at clotting risk
Temporary risk factors like long immobilization or travel
The filter provides a protective barrier, especially when standard medications are not safe or effective.
What happens during the procedure?
IVC filter insertion is a minimally invasive procedure, usually done in a catheterization lab or interventional radiology suite:
You’ll lie on your back, and a local anesthetic will be given at the insertion site (typically in the groin or neck)
A small catheter is inserted into a large vein and guided into the inferior vena cava
The filter is then released and expands to attach to the walls of the vein
The catheter is removed, and pressure is applied to stop bleeding
The procedure usually takes less than 1 hour, and you may be discharged the same day or after brief observation.
What might I feel?
Mild sting or pressure during local anesthesia
Slight pressure or pulling sensation during catheter placement
Temporary soreness or bruising at the insertion site
Generally, the procedure is painless and well tolerated
Most patients remain comfortable throughout, and sedation is usually not necessary.
What happens after the procedure?
The insertion site is bandaged and monitored
You may need to lie flat for a short period
You can usually resume normal activities within 24–48 hours
Follow-up imaging may be done to ensure proper filter placement
Some filters are temporary and may be removed once the clot risk is resolved
