New research in JAMA Surgery concludes that IVC filters don’t save lives in trauma patients, who are at increased risk of bleeding and thrombosis, and the devices should not be placed in trauma patients in an effort to decrease all-cause mortality.
“The research herein demonstrates no significant difference in survival in trauma patients with vs without placement of an IVC filter, whether in the presence or absence of venous thrombosis. The use of IVC filters in this population should be reexamined because filter removal rates are low and there is increased risk of morbidity in patients with filters that remain in place,” the study concludes.

Should not be placed in trauma patients
“The use of IVC filters in this population should be reexamined because filter removal rates are low and there is increased risk of morbidity in patients with filters that remain in place,” the researchers said. “Given the expected morbidity of long-term IVC filter use, filters should be removed as soon as a patient’s contraindication to anticoagulation resolves.”
“Overall, these data indicate that IVC filters should not be placed in trauma patients in an effort to decrease all-cause mortality.”
Litigation against the makers of IVC filters is one of the largest mass torts today. “All these products are defective,” Mass Tort Consultant John Ray said, speaking in a webinar presented by The National Trial Lawyers. “I cannot say that one product is less defective than other.”
- There are 886 cases in Bard IVC Filter Litigation in MDL 2641 before Judge David G. Campbell in US District Court in Arizona.
- There are 993 cases in Cook Medical IVC Filter Litigation in MDL 2570 before Chief Judge Richard L. Young in US District Court for the Southern District of Indiana. The defendants are Cook Medical, LLC and Cook Inc., both of Bloomington, IN, and William Cook Europe APS, Bjaeverskov, Denmark.
- Cordis IVC Filter Litigation is centered in the California state courts, where hundreds of cases are up for consolidation. Cordis Corporation is organized under the laws of Florida, with its principal place of business in Fremont, California.
- There is no MDL for Boston Scientific Corp IVC Filter Litigation. “We believe it is possible that more cases will be filed and a motion for consolidation and transfer may be formed in an effort to form an MDL,” says Ray.
- Similarly, there is no MDL for cases against Rex Medical and Argon Medical. Plaintiffs have filed cases in the Philadelphia Court of Common Pleas before Judge Arnold New, who has assigned them to the complex litigation track.
Venous thromboembolism is a significant cause of death in the United States. Approximately 900,000 patients per year have a clinically significant deep vein thrombosis or pulmonary embolism. Since the invention of the permanent percutaneous IVC filter in 1973 and the retrievable IVC filter in the 1990s, its use has become a standard part of treatment for select patients with acute lower-extremity venous thrombosis who cannot receive anticoagulation.
