title: [Expandable stents and composite prosthesis].
abstract: Today, numerous expandable and mixed silicone metallic stents for trachea and bronchi are available. Among the many technical propositions, Nitinol is a new alloy with promising potential, offering the advantage of shape memory. The right stent is the one which best meets the needs of the individual stenotic situation as evaluated by endoscopy and CT. Sufficient experience has been acquired only with the Dumon stent, giving exact information about its qualities and possible complications. The new stents are thinner. Some can be inserted under fluoroscopic and fibroscopic control. They are presumed to produce fewer complications an provide answers to some still unresolved questions such as dyskinesia or stenosis on short bronchi. They appear to be more easily inserted on the tracheo-bronchial tree. More experience is needed to satisfactorily identify specific indications and contraindications. A prospective registry will be important to obtain comparative information more quickly.
