[Percutaneous extraction of a silicone catheter 5 years after its migration in the pulmonary artery].

The authors describe a case of percutaneous extraction of a piece of silicone-coated catheter, 5 years after its embolisation in the pulmonary artery and the results of electronic microscopic study of the specimen. The discussion provides the factors indicating extraction which is relatively easy with this technique irrespective of the chronicity of embolisation, in order to avoid infectious complications.
