Anesthesia for tracheal reconstruction and transplantation

Area of Science:

• Thoracic surgery
• Anesthesiology
• Regenerative medicine

Background:

• Large airway lesions present significant surgical and anesthetic challenges.
• Limited surgical options exist for extensive tracheobronchial resections.
• Anesthesiologists and surgeons face considerable obstacles in managing these complex cases.

Purpose of the Study:

• To review recent advancements in the anesthetic and surgical management of tracheobronchial lesions.
• To highlight novel approaches for patients requiring significant airway resection.

Main Methods:

• Review of technological advances in airway surgery.
• Evaluation of extracorporeal life support systems (pump-driven and pumpless).
• Assessment of progress in tracheal transplantation techniques, including synthetic scaffolds and stem cell applications.

Main Results:

• Extracorporeal life support enables prolonged apneic airway surgery.
• Tissue-engineered tracheal transplantation has advanced significantly, utilizing synthetic structures and autologous stem cells.
• Novel approaches offer new possibilities for patients with large airway lesions.

Conclusions:

• Tissue-engineered airway transplantation provides curative options for previously inoperable patients.
• Management of these patients requires close perioperative collaboration among surgeons, anesthesiologists, and intensivists.
• Advanced extracorporeal life support systems are crucial for successful surgical outcomes.
