Tracheal stent SAP

silicone

With a more robust wall, this model is very resistant to max compression. When any stent is put under a strength test that compresses it with loads that increase gradually, the stent’s paulatine deformation takes place until it reaches the cession point. Here, the prosthesis suffers a higher deformation, with a notorious reduction of its radial resistance to flattening. This is called the break point, which is about 900 g/cm2 in a classical stent. In the Stening® High Pressure Stent the tolerance to compression increases surpassing the 2000 g/cm2. Its wall’s thickness increase is accompanied by an inevitable reduction in the area available for air flow. Indications: Tracheal neoplasms with a solid extrinsic compression A severe tracheal compression that occurs again after the dilatation In replacement of a classical stent that collapse by extrinsic compression Introduction technique: The procedure will take place under general anaesthesia. The implant of these type of prostheses can be made directly through the work channel of the tracheoscope or bronchoscope. A conventional introducer for silicone prostheses can be used as well. A rigid endoscope will be used to access the airway. The length and diameter of the area that the stent will cover must be established correctly. If you want to know the length of the area, you can mark the tracheoscope when its extreme is located at the end of the injury. Repeat the process once the tracheoscope is moved up to the beginning of the injury. The diameter of the trachea or bronchi must be estimated by comparing it with the diameter of the endoscope used.
