It consists on a straight tracheal stent with a thinner wall. This docility makes its implant and removal easier.
It has a special utility after the neoplastic and endotracheal tissue’s resection, when the affection lacks of a compressive component.
A thinner wall of the prosthesis significances an increase in the stent cross section surface destined for ventilation.
The relation between the surface that occupies the wall and the clearance available for ventilation is modified favourably.
In the other way round, it can be expected a lower resistance to extrinsic compression and a decrease of the cession point.
The wall’s thickness decrease makes easier the introduction of the prosthesis inside the ejector or the bronchoscope. As well as the implant and removal manoeuvres.
Primary or secondary tracheal neoplasm
After laser resection, cryotherapy or electrocautery, to maintain the airway opened
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.
