[Migration of the catheter of a totally implantable venous system. A rare mechanical complication].

Catheter migration, represents a rare, mechanical complication following the use of totally implantable venous devices. A case, in which the catheter was inserted into the right internal jugular vein by percutaneous route, without radiological control, is described. Following the chemotherapy infusion drugs, the patient developed a catheter displacement and subcutaneous extravasation. Etiological hypotheses and modalities of prevention are discussed.
