Furthermore, they have traditionally been described to pose lower cardiopulmonary risks compared with anterior mediastinal masses. Studies on posterior mediastinal masses are even more limited in the pediatric population. We present a case of a large posterior mediastinal mass in a 4-year-old child who presented with extremely difficult airway management during endobronchial intubation due to severe external compression that led to use of an adapted airway management technique with a rigid airway exchanger for lung isolation. Due to the pathology of the mass, a tracheal tear was encountered during surgical dissection and the patient required emergent venovenous extracorporeal membrane oxygenation to allow for successful airway repair and complete resection of the mass.<\/jats:p>","DOI":"10.1177\/1089253220960267","type":"journal-article","created":{"date-parts":[[2020,10,1]],"date-time":"2020-10-01T02:37:48Z","timestamp":1601519868000},"page":"349-354","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Resection
