Curtis RM, Vogt K, Parry N, et al. - In view of the uncertainty concerning the role for retrievable inferior vena cava filters (rIVCF) use for pulmonary embolism (PE) prevention in high risk trauma patients, researchers here examined if in high risk trauma patients, insertion of rIVCF for PE prophylaxis results in a clinically meaningful reduction (> 24 h) in time that patients are left unprotected from PEs. In this single center, randomized control trial, they included 42 adult (age > 18 years) trauma patients who were identified to be at high risk for PE by EAST criteria and were unable to receive pharmacologic prophylaxis for at least 72 h; patients were randomized to receive a rIVCF or to not have a rIVCF placed. Based on observations, it is feasible to study retrievable inferior vena cava filter use for PE prevention, displaying a 53 h difference in time left unprotected. There were no complications of retrievable inferior vena cava filters, and 100% retrieval rate was achieved in patients who survived.
