Impossible airway requiring venovenous bypass for tracheostomy

Area of Science:

• Otolaryngology
• Anesthesiology
• Thoracic Surgery

Background:

• Tracheal stenosis requires definitive airway management when resection or dilation fails.
• Previous attempts at surgical airway placement can complicate subsequent procedures due to scar tissue.
• Managing complex airways necessitates advanced techniques and multidisciplinary collaboration.

Purpose of the Study:

• To describe the successful management of a patient with severe tracheal stenosis and a history of failed airway intervention.
• To illustrate the utility of regional anesthesia combined with venovenous bypass for complex surgical airway creation.
• To emphasize the role of advanced monitoring and teamwork in critical airway scenarios.

Main Methods:

• A combination of regional anesthesia and venovenous bypass was employed for surgical airway management.
• Cerebral oximetry was utilized for continuous monitoring of brain oxygenation.
• A multidisciplinary team approach involving anesthesiology, thoracic surgery, and otolaryngology was implemented.

Main Results:

• Successful creation of a surgical airway was achieved despite significant anatomical challenges and prior surgical site scarring.
• Early detection of a potential intraoperative oxygenation issue via cerebral oximetry allowed for timely intervention.
• The patient's life was preserved through the emergent intervention facilitated by the specialized approach.

Conclusions:

• Regional anesthesia and venovenous bypass represent a viable strategy for complex surgical airway management in tracheal stenosis.
• Continuous cerebral oximetry is a valuable tool for monitoring and guiding interventions during high-risk airway procedures.
• A multidisciplinary team is essential for optimizing outcomes in challenging surgical airway cases.
