IVC Filter Migration
The initial models of IVC filters, which were designed to be permanent, were used for patients at risk for blood clots and pulmonary embolisms. These filters were inserted into the inferior vena cava, the largest vein in the human body. After implantation, these devices would catch blood clots before they could continue through the vein into the lungs. They proved to be an effective method for preventing deadly pulmonary embolisms.
Problems with Permanent IVC Filters with the Option to Retrieve
In the early 2000s, temporary versions of these filters were created, known as permanent IVC filters with the option to retrieve. Unlike their predecessors, these filters were able to be removed once the risk of blood clots was diminished. In many cases, the devices were left in the body as they were sold as permanent IVC filters with the option to retrieve but could be left in place.
Doctors and patients were not warned of the risks of prolonged treatment. Manufacturers were ignoring the reports of adverse side effects that were coming in with alarming frequency.
IVC Filter Migration
One of the most common adverse side effects of permanent IVC filters with the option to retrieve is the device’s tendency to tilt, dislodge itself and migrate. In fact, a 2010 study conducted by the FDA found that out of 921 reports, migration was the most common complaint, occurring in 328 patients. Additional complications included filter fractures, vein wall punctures, and filter detachment.
Misplacement to intracardiac locations is particularly dangerous, as this refers to the device migrating to nearly any area of the heart. In most of these cases, the complication required surgery to retrieve the device, and in some circumstances, the device could not be retrieved.
Lawsuits Against IVC Manufacturers
As a result of the defective IVC filter design and failing to warn consumers of the devices’ potential risks, manufacturers of the IVC filters are in for an extensive court battle. Currently, there numerous lawsuits against C.R. Bard and Cook Medical, and the numbers continue to rise.
