Airway Obstruction Due to Tracheomalacia Caused by Innominate Artery Compression and a Kyphotic Cervical Spine Chia-Hsin Liu, MD, Wen-Sheng Huang, MD, Hong-Hau Wang, MD, Chin-Pyng Wu, MD, PhD, Chih-Feng Chian, MD, Wann-Cherng Perng, MD, Chen-Liang Tsai, MD The Annals of Thoracic Surgery Volume 99, Issue 2, Pages (February 2015) DOI: /j.athoracsur Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

Fig 1 (A) Left (inspiration). Sagittal neck computed tomography revealed that the trachea was held between the innominate artery (star) and a kyphotic cervical spine (thick arrow) front and rear. Right (expiration). The tracheal lumen further collapsed at forced expiration. (B) Axial chest computed tomography (CT) showed that the innominate artery (star) was located more to the left and directly compressed the trachea, creating a crescent shape, along with invagination of the membranous posterior wall during expiration (thin arrow).
