Cervical aortic arch with anomalous origin of the left subclavian artery from Kommerell's diverticulum

Abstract

SummaryWe report here a patient with right cervical arch and anomalous origin of the left subclavian artery from the diverticulum of Kommerell. This uncommon abnormality can give rise to symptoms due to compression of the trachea and esophagus. Unlike right aortic arch with mirror image pattern of branching, however, this abnormality is seldom associated with intracardiac defects. Most patients are asymptomatic, and surgery is indicated only if severe symptoms are present.
