Notre expérience du filtre de Greenfield. A propos de 40 observations comparées à 40 filtres-ombrelles et 40 clips.

: Results of interruption of the vena cava for thromboembolic complications are reported. Greenfields filter was used in 40 cases, its introduction appearing to be a more delicate procedure than when other materials (caval clip in 40 cases and Mobin-Uddin's filter in 40 cases) were used. Results with regard to recurrence of emboli were comparable for the different materials, but Greenfield's filter becomes thrombosed less often and provokes fewer major sequelae.
