[Use of the Kimray-Greenfield filter in the prevention of pulmonary embolism].

The authors analyse the results of the application of 14 Kimray-Greenfield filters; there was neither pulmonary embolism, nor thrombosis of the vena cava inferior nor any other complication. These good results, like those of much more important series which have recorded, prompt us to use the Kimray-Greenfield filter in normal cases. The authors also think that the qualities of the filters mean that they can be used systematically in a preventive capacity, in certain cases where the risk of serious thrombo-embolic illness is especially high and impossible to prevent effectively, owing to specific circumstances.
