[Complications of implantable sites].

Approximately 50,000 implantable sites are prepared each year in France because of the undeniable advantage for the treatment of patients requiring long-duration intravenous infusions. The benefits of this technique must not overshadow the mechanical risks inherent in their installation and complications related to their use: infections, thromboembolic events. Clear, precise, and adapted treatment protocols must be established and rigorously implemented by the healthcare team. Information notes for the patients concerning the risks involved and warning signs must be written in order to be able to institute appropriate treatment rapidly.
