Tracheal compression by brachiocephalic arterial trunk: a rare cause of failed endotracheal intubation

Abstract

Encountering and managing an unanticipated difficult airway are among the many challenges faced by anaesthesiologists. Due to the intimate anatomical relationship between the thoracic vasculature and the trachea, an anatomical variation could potentially lead to airway compression. This clinical case report documents a failed intubation in an adult patient caused by undiagnosed extrinsic tracheal compression from the brachiocephalic arterial trunk, a rare condition. After a thorough investigation and diagnostic clarification, a safe anaesthetic plan following the predictable difficult airway guidelines was established to enable surgery. Anaesthesiologists should consider rare vascular causes as potential contributors to difficult airway scenarios, thereby enhancing their expertise.
