People who receive IVC filters are at a higher risk for pulmonary embolism. Inferior vena cava filters may also be suggested for patients who experienced a trauma, or for individuals who have difficulties with mobility.

Once the IVC filter has reached its proper posture, the physician releases it. The IVC filter then opens and becomes nestled in the blood vessel, able to catch blood clots that develop in the legs. It's placed within the abdomen, or sometimes, in the leg.

But delayed complications, such as filter fracture, migration, IVC thrombosis and recurrent PE, can cause disease and death. Fracture and migration are the most common complications, which are also associated with arterial piercing, bacterial infection, and bleeding.

Complications arise when the filter migrates to areas such as the lungs or heart, which is referred to as a cephalad migration. When the IVC filter migrates in a downward motion, it is known as a caudal migration. Migration often makes retrieval difficult or impossible without surgery.

Perforation occurs when one or more of the struts of the filter puncture the wall of the IVC. Over time, an IVC filter can erode the walls of the IVC and become embedded in the tissue. Perforated filters are very difficult to remove, and they can cause fatal bleeding if left untreated.

Over time, the struts, which are essentially the legs of the device, can break off. When they're no longer placed in the inferior vena cava, fractured struts migrate to the heart or lungs. They can also migrate to the kidney, liver or spine. Some people experience ongoing chest pain, whereas others lose their lives.

The process is a loophole that allows manufacturers to skip clinical testing and put the product straight to market. It wasn’t until hundreds of people experienced issues with their IVC filters that the FDA had begun to address the problem.
