Compression of trachea and left main bronchus by arch aneurysm

We report on the case of a 70-year-old woman who presented dyspnea. Contrast-enhanced computed tomography of the chest revealed the compression of the lower part of the trachea and left main bronchus by an aneurysm of the ascending aorta and aortic arch. Although we performed a replacement of the ascending aorta and aortic arch, we were unable to relieve the stenosis of the trachea and bronchus. By the suspension of the posterior wall of the native aneurysm, we were able to successfully relieve the compression and alleviate the respiratory insufficiency.
