Treatment of iatrogenic injury of membranous trachea with intercostal muscle flap.

Iatrogenic injuries of the membranous trachea are rare but potentially lethal, and most commonly require surgical treatment. Such injuries occur intraoperatively during specific thoracic surgery procedures or are associated with endotracheal anesthesia. Special technical difficulties in managing them surgically are encountered when lacerations are in proximity to the rigid rings of the trachea because of the lack of membranous tissue distal to the tear.
