Who invented the IVC filter?

The first IVC filter was created by Kazi Mobin-Uddin, MD who published his findings in 1969 in the New England Journal of Medicine. The Mobin-Uddin filter was later replaced by the Greenfield filter developed by Lazar Greenfield which had a lower rate of filter related complications.

When was the IVC filter invented?

Inferior vena cava (IVC) filters were first introduced in 1967 by Kazi Mobin-Uddin and later improved by Lazar Greenfield in the 1980s becoming a major component of catastrophic pulmonary embolism prevention.

What is the purpose of a Greenfield filter?

The filter catches blood clots and stops them from moving up to the heart and lungs. This helps to prevent a pulmonary embolism. The IVC filter is placed through a small incision in a vein in your groin or neck. A thin, flexible tube (catheter) is inserted into this vein.

Is a Greenfield filter MRI safe?

They conclude that, while most Greenfield filters respond to a magnetic field, the chance of migration of a filter because of an MRI scan is small. Therefore, MRI scanning of patients with Greenfield filters has little risk.

How many IVC filters are there?

There are two types of IVC filters that can be placed. Your doctor will determine which type of filter is right for you. These filters are placed in patients that have a permanent contraindication or complication to anticoagulation medications, patients that are elderly, or have a poor prognosis (survival < 6 months).

How long does a Greenfield filter last?

The U.S. Food and Drug Administration (FDA) recommends removing temporary IVC filters after 29-54 days. While this is not very long, it should provide enough time for the acute threat to pass or to find another solution that can work on a long-term basis.

Can a Greenfield filter be removed?

A retrievable IVC filter may be removed when the risk of a blood clot traveling to the lungs has passed or if you can take blood thinners. Your doctor may recommend removing the filter when it’s no longer needed.

Where is the Greenfield filter?

Greenfield filters for prevention of pulmonary emboli may be placed in the inferior vena cava by surgical cutdown or by percutaneous insertion through the femoral or jugular veins.

How long do Greenfield filters last?

How much compensation do you get for an IVC filter?

Based on the IVC filter verdicts and the history of mass tort litigation, settlements may average between $100,000 and $500,000 for significant injury cases but there will certainly be cases that settle higher and lower than that payout range.

How long do IVC filters last?

Retrievable IVC filters may be removed once the risk of a clot traveling to the heart and lungs passes, usually after about six months. If blood thinners are unusable and/or the risk of clots continues, a removable filter may remain in place for an extended period of time.
