Here are the typical steps for deploying a silicone Y stent in the trachea:
Prepare the patient under general anesthesia with rigid bronchoscopy. The airway is often predicated first.
Insert the bronchoscope and assess the trachea and mainstem bronchi to determine the proper stent size and position. Measurements are taken
The compressed Y stent is loaded onto the insertion catheter/deployment device. It is lubricated and passed through the bronchoscope.
Position the stent's central portion in the trachea, with the two arms oriented towards the left and right main bronchi. Align any markers on the stent.
Under direct visualization, the stent is deployed by pulling back the constraining sheath and allowing the stent to expand.
Proper stent position across the carina and in the bronchi is confirmed. Flaring of the stent ends helps retain it.
Adjustments can be made by forceps if needed. Stent position is reconfirmed.
Once proper stent deployment is achieved, the delivery device and bronchoscope are gently removed.
A bronchoscopy is repeated to ensure the stent opened correctly and is in a stable position before ending anesthesia.
Post-procedural imaging like chest X-ray is done to document stent placement.
Careful sizing, lubrication, and visualization during deployment are key to successfully placing silicone Y stents. Patients require regular monitoring and stent maintenance long-term.
