Abstract:
A 78-year-old female presented to our institution with a dry cough and dyspnea. Chest computed tomography( CT) revealed tracheal stenosis caused by compression from a brachiocephalic artery with a bovine aortic arch. Subsequently, surgery was performed in which the brachiocephalic artery was resected, and a total arch replacement using a four-branched graft was completed. We paid particular attention to the graft branches, making sure to avoid contact with the trachea. Both the patient's cough and dyspnea dissipated after the surgery, and a CT revealed the tracheal stenosis had been completely relieved. The patient has remained in good condition for the past three years since the surgery showing no respiratory symptoms or thoracic aortic disease. Because the bovine aortic arch is a known risk factor for thoracic aortic disease, rather than simply reconstructing the brachiocephalic artery, we chose a more aggressive surgical treatment to prevent any possible future thoracic aortic disease.
