May 2, 2014 — When inferior vena cava (IVC) filters are implanted in patients with venous thromboembolism (VTE), they have a lower risk of pulmonary embolism (blood clots in the lungs) but a higher risk of recurrent VTE, according to a study published in the Journal of the American College of Cardiology.
The study evaluated the effectiveness of IVC filters in patients with VTE and a known risk of bleeding. Researchers analyzed data on 344 patients with an IVC filter who were matched with 344 patients who did not receive a filter. Patients were tracked for 30 days post-implantation.
Both groups had a similar risk of death. However, there were significant differences for complications like pulmonary embolism and recurrent VTE:
- Pulmonary embolism: Occurred in 4.9% of non-filter patients vs. 1.7% of IVC filter patients.
- Recurrent VTE: Occurred in 0.06% of non-filter patients vs. 6.1% of IVC filter patients.
The researchers emphasized that the study was not large enough to imply a causal relationship between IVC filters and complications. However, it is concerning because recurrent VTEs can be deadly.
What is VTE?
Venous thromboembolism is a life-threatening medical condition that begins when a blood clot grows inside a deep vein (called deep vein thrombosis or DVT). If this blood clot breaks loose, it can potentially travel in the bloodstream, get trapped in the lungs, and cause a pulmonary embolism. This combined event is called a VTE.
