“…The most common indication for airway surgery using ECLS was primary malignancy of the airways, with 27% of cases in the literature (n=45/168). The histological subtypes were: squamous cell carcinoma (SCC) in 15 cases ( 18 , 36 , 37 ), adenoid cystic carcinoma (ACC, n=10) ( 7 , 15 , 24 ), neuroendocrine tumor (NET, n=3) ( 5 , 18 ), sarcoma (n=2) ( 31 , 38 ), mucoepidermoid carcinoma (MEC, n=2) ( 12 , 21 ) and adenocarcinoma (n=1) ( 39 ). Based on tumor localization, the type of resections was: carinal resection (n=16), segmental tracheal resection (n=9), pulmonary bronchial sleeve resections w/o carina (n=10), airway replacement with stented aortic matrices (n=4), left main bronchus resection w/o (Hemi-)carina (n=3) and resection of the membranous tracheal wall (n=3).…”
