Use of laryngeal mask airway with continuous transcutaneous PCO2-monitoring for crico-tracheal resection requiring intermittent prolonged apnea in a pregnant woman

Subglottic stenosis (SGS) is characterized by a narrowed upper airway extending from just below the vocal folds to the lower border of the cricoid cartilage (1). SGS is either a congenital or an acquired condition of unknown pathophysiology generally accompanied by formation of scar tissue, fibrosis, and enhanced inflammation (2, 3). As the affected tissue contains estrogen receptors, growth hormones influence and impact its severity (2). Although several conservative and invasive treatment strategies exist, only crico-tracheal resection (CTR) can remove the constricting tissue completely and offers recurrence-free survival (4).
