Enrollment begins for PRESERVE, large study of IVC filters
As of mid-December, researchers have activated the first 10 medical sites and enrolled the first nine patients in a study that will determine the safety and effectiveness of inferior vena cava filters, small, cage-like devices implanted to prevent life-threatening blood clots from reaching the heart or lungs. While vein filters have been in use for years, PRESERVE (Predicting the Safety and Effectiveness of Inferior Vena Cava Filters), is the first large-scale, multispecialty, prospective clinical research trial that will evaluate their real world safety and effectiveness. The inferior vena cava is the main vessel returning blood from the lower half of the body to the heart.
