In recent years, emergency room physicians routinely implant IVC filters in patients suffering serious injuries due to trauma. IVC filters are also routinely used in patients undergoing joint surgery. In both instances, the placement of the filter is supposed to reduce the risk of embolism – however a recent study reveals no correlation between placement of IVC filters and patient survival rates. The results are concerning to say the least.
IVC Filter Study Results
A study led by Dr. Shayna Sarosiek, conducted at Boston University School of Medicine reveals that IVC filters are dangerous, and provide virtually no survival advantage to patients.
The study, published in JAMA Surgery, examined records of trauma patients that previously received an IVC filter to prevent blood clots and pulmonary embolism. The study involved records from over 450 IVC recipients, as compared with 1,343 controls. The study revealed no decrease in death rates who received an IVC filter after trauma, and concluded that there was “No significant difference in survival in trauma patients with versus without placement of an IVC filter, whether in the presence or absence of venous thrombosis.”
The study also revealed that after 3.8 years, only 8 percent of patient filters had been removed. IVC filters were not designed or intended for long-term placement; in fact, the FDA recommends removal within approximately 60 days of initial placement.
Additional Concerns with IVC Filters
The longer an IVC filter remains implanted, the more increased the chances of the filter tearing, migrating, fracturing, shattering, and leading to additional, serious complications. In the study, researchers stated, “given the expected morbidity of long-term IVC filter use, filters should be removed as soon as a patient’s contraindication to anticoagulation resolves.”
Even though they are supposed to be easily retrievable and removable, IVC filters are difficult to remove, and in some cases, are never removed because they become embedded or fracture and migrate throughout the body.
The study revealed that 92% of patients with IVC filters still had the filter as long as four years after implantation. Many patients may not even be aware that they have an IVC filter, another complicating factor.
