Filter placement by ultrasound technique at the bedside.

ABSTRACT

Vena cava filtration devices are commonly inserted for the prevention of fatal pulmonary emboli. Several imaging methods are used today to direct device placement. Bedside insertion has several advantages, particularly in the critically ill patient. Imaging techniques include bedside fluoroscopy, transperitoneal ultrasound, and intravascular ultrasound. We have now successfully placed 10 transfemoral vena cava filters by use of intravascular ultrasound at the patient's bedside. This appears to be a feasible method for filter insertion.
