Tracheal perforation. A complication associated with transtracheal oxygen therapy

Area of Science:

• Pulmonology
• Medical Device Complications
• Respiratory Medicine

Background:

• Transtracheal oxygen therapy (TTOT) is an established method for delivering supplemental oxygen to patients with chronic hypoxemia.
• TTOT involves the surgical placement of a transtracheal catheter directly into the trachea.
• Potential complications associated with TTOT include infection, bleeding, and airway injury.

Observation:

• A 73-year-old woman using a transtracheal oxygen catheter experienced sudden respiratory distress and subcutaneous emphysema.
• Bronchoscopic examination identified three perforations in the posterior tracheal wall and a blind pouch connected to one perforation.
• The patient's tracheal perforations showed complete healing on subsequent bronchoscopic evaluations.

Findings:

• The study suggests that the tracheal perforations likely occurred during the initial placement of the transtracheal oxygen catheter.
• The development of subcutaneous emphysema and respiratory distress was directly linked to the tracheal wall defects.
• The natural healing process of the tracheal wall was demonstrated, resolving the observed perforations.

Implications:

• This case highlights a rare but serious complication of transtracheal catheter insertion.
• It underscores the importance of careful technique during transtracheal catheter placement to minimize airway trauma.
• The findings suggest that tracheal perforations from catheter placement may be self-limiting and heal without surgical intervention.
