A safe technique for introduction of the Kimray-Greenfield filter.
A modification in the introduction of the Kimray-Greenfield filter is described. Rather than advancing the stylet toward the Luer-lok assembly and thereby discharging the filter, the authors propose positioning the carrier containing the closed filter farther into the inferior vena cava, then withdrawing the catheter and carriage while holding the stylet in place. This method reduces the chance for damaging the caval wall.
