Anthony was inserted with a retrievable IVC filter on Sept. 11, 2011 at Carson Tahoe Regional Medical Center in Carson City, Nevada, after a history of blood clots. An IVC filter is a cage-like device inserted the vena cava, the largest vein in the body, and is designed to catch blood clots before they reach the heart or lungs, resulting in pulmonary embolism (PE).
Five years after the procedure, when he began experiencing shortness of breath and chest pain, Anthony went to the emergency room at NorthBay Medical Center in Fairfield, California, on March 31, 2016.
A CT scan of Anthony’s chest revealed blood clots in both of his lungs, known as a “bilateral acute pulmonary embolism,” a condition the IVC filter was designed to prevent. According to the lawsuit, the CT scan also revealed that the IVC filter was “tilted, eroded into the lumen, and migrated.”
The hospital discharge summary noted that the migrated IVC filter could have been the source of the pulmonary embolism.
Many IVC filters are made to be permanent, but more modern designs are intended to be temporary. In fact, the U.S. Food and Drug Administration (FDA) recommends that a temporary, or retrievable IVC filter, should be removed 29 to 54 days after insertion.
However, according to national data retrievable IVC filters are often left in permanently, increasing the patient’s risk for the device to tilt, migrate, perforate or fracture. Despite the lack of clinical studies to prove the safety and efficacy of the filters, their use continues to rise year after year.
More than 3,000 lawsuits have been filed nationwide against retrievable IVC filter manufacturers such as Rex Medical L.P., Argon Medical Devices, Cook Medical Inc., C.R. Bard, and B. Braun Medical alleging injuries related to failed IVC filters.
