The percutaneous placement of inferior vena cava filters is traditionally carried out in angiosuite or operating room using fluoroscopy and infusion of iodinated contrast for proper positioning of the device. However, for patients hospitalized in intensive care units under poor conditions for transportation, and for patients with impaired renal function, their displacement and the nephrotoxicity of the iodinated contrast agents are frequently matters of concern. Thus, the bedside placement of inferior vena cava filters guided by ultrasound may be a reasonably safe and attractive alternative for these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
