Kommerell Diverticulum: A Rare Cause of Dyspnea and Dysphagia

Abstract

Kommerell's diverticulum (KD) is a congenital dilatation of the distal portion of the aortic arch that is usually located at the origin of an aberrant right subclavian artery (ARSA) or the aberrant left subclavian artery (ALSA). We describe here a 40-year-old male patient with a right-sided aortic arch (RAA) with ligamentum arteriosum (LA) and ALSA originating from the KD. The applied to our outpatient clinic with a history of dyspnea and dysphagia that had persisted for the last year. The patient underwent chest computed tomography (CT) in our clinic, revealing ALSA-level KD in RAA with ligamentum arteriosum. Surgical resection of KD and LA was planned based on the symptoms. NE was resected from the descending aorta and ALSA was transferred to the left carotid artery, and the patient was discharged 6 days after the operation without complications. After the operation, the patient's dyspnea and dysphagia subsided completely.
