This case study highlights a rare instance of double-level tracheal stenosis following prolonged mechanical ventilation. An endoscopic procedure successfully treated the complex airway narrowing in a 43-year-old male patient.
Area of Science:
- Pulmonology
- Medical Case Reports
- Surgical Innovation
Background:
- Post-intubation tracheal stenosis is a known complication of mechanical ventilation.
- Double-level tracheal narrowing is an exceptionally rare presentation.
- Progressive respiratory impairment necessitates investigation of airway obstruction.
Purpose of the Study:
- To report a rare case of double-level tracheal stenosis.
- To illustrate diagnostic findings using advanced imaging.
- To demonstrate successful endoscopic management of complex tracheal stenosis.
Main Methods:
- A 43-year-old male with a history of prolonged mechanical ventilation presented with respiratory distress.
- Computed tomography with 3D reconstruction was utilized for detailed airway assessment.
- An endoscopic procedure was performed for treatment.
Main Results:
- Diagnostic imaging revealed complex tracheal anatomy with stenosis at two distinct levels.
- The patient's progressive respiratory impairment was attributed to the double-level tracheal stenosis.
- The endoscopic intervention was technically successful.
Conclusions:
- Complex tracheal stenosis, even at double levels, can be effectively diagnosed and managed.
- Endoscopic procedures offer a viable treatment option for challenging tracheal stenosis.
- This case expands the understanding of post-intubation airway complications.

Tracheostomy Decannulation
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Endotracheal Intubation I: Procedure
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...
