Specialized care for patients who may need protection from pulmonary embolism due to blood clots. IVC filter insertion and retrieval are image-guided procedures used in selected cases to help prevent blood clots from travelling from the deep veins of the legs or pelvis to the lungs.
Consultant, Sir Ganga Ram Hospital
An inferior vena cava (IVC) filter is a small, matal device placed inside theinferior vena cava, the large vein that carries blood from the lower part of thebody back to the heart. The filter is designed to catch certain blood clots travelling from the deep veinsof the legs or pelvis before they reach the lungs, where they could cause apotentially life-threatening condition called puimonary embolism (PE).
An IVC filter may be considered for patients at risk of pulmonary embolism when anticoagulant treatment cannot be used or when specific clinical situations justify filter placement.
IVC filter insertion is a minimally invasive, image-guided procedure in which a filter is placed inside the inferior vena cava to reduce the risk of certain blood clots travelling to the lungs.
The doctor reviews the patient's medical history, current condition, blood clot history, medications, and relevant imaging reports.
The medical team explains the procedure, its potential benefits and risks, and any required preparation. Blood tests and imaging may be performed when indicated.
The procedure is generally performed through a small access point in a vein, commonly in the neck or groin. A catheter is guided into the inferior vena cava under imaging guidance, and the filter is released at the appropriate location.
The patient is monitored for potential complications and receives instructions about medications, follow-up appointments, and ongoing management of the underlying clotting condition.
When the risk that justified filter placement has passed, the filter should be reassessed for removal. Retrieving the filter, when possible, may help reduce long-term risks such as filter fracture, migration, or additional clot formation.
May reduce the risk of certain blood clots reaching the lungs in appropriately selected patients.
Can provide an option when anticoagulation is temporarily or persistently contraindicated.
Retrievable filters may be removed when they are no longer required.
Insertion and retrieval are generally performed using minimally invasive, image-guided techniques.
Bleeding, bruising, or infection at the access site.
Filter movement, tilting, fracture, or penetration of the vein wall.
Blood clot formation in or around the filter, including obstruction of the inferior vena cava.
Difficulty or failure of filter retrieval.
Contrast-related reactions or other procedure-related complications.
Dr. Anadi Gupta, MD, FVIR, EBIR, is a Consultant at Sir Ganga Ram Hospital with a focus on vascular and endovascular interventions.
His areas of practice include DVT thrombectomy and catheter-directed thrombolysis, IVC filter insertion and retrieval, peripheral arterial angioplasty and stenting, central venous interventions, varicose vein treatment, dialysis access procedures, and selected embolization treatments.

Not for everyone. Anticoagulants are the main treatment for most DVT cases because they help prevent clot extension and new clots. Thrombectomy may be considered in selected patients with extensive clots or severe symptoms after evaluating the potential benefits and risks.
It is a minimally invasive, image-guided procedure performed through vascular access rather than a large surgical incision. However, it requires careful monitoring because clot-dissolving medication can cause serious bleeding.
The duration varies depending on the clot's location and extent, the technique used, and the patient's condition. The treating team can provide an estimate after reviewing the investigations.
Often, yes. Many patients need anticoagulant medication after thrombectomy or thrombolysis to prevent recurrent clots. The medication and duration depend on individual risk factors and the treating doctor's advice.
Recovery varies according to the severity of DVT, the procedure performed, other medical conditions, and any complications. Some patients require hospital monitoring, and follow-up is important after discharge.
Yes. Clots can recur even after successful treatment. Anticoagulation when prescribed, management of risk factors, and follow-up care are important in reducing the risk of recurrence.
Seek emergency medical care if you experience sudden breathlessness, chest pain, coughing up blood, or fainting, as these may indicate pulmonary embolism. New or worsening leg swelling and pain also require prompt medical assessment.
