[Indications of partial interruption of the inferior vena cava in pulmonary embolism].

Forty years after the first implantation of caval filters, there is still no indication for implantation validated by a controlled clinical trial. This fact may be explained by our poor understanding of the evolution of thromboembolic disease, especially in certain groups of patients. The absolute contra-indications to heparin therapy would seem to be a logical indication for a caval filter.

[Long-term follow-up of a rare complication of vena cava filters: complete and spontaneous rupture of the filter].

Complete spontaneous rupture of a percutaneous caval filter produced two equal parts. Long-term follow-up showed that the filter then remained stable with no complications. This case emphasizes the importance of long-term follow-up of patients with caval filters.
