Distal Limited Open Stenting for Aortic Diverticulum in the Right Aortic Arch.

An aortic diverticulum, including Kommerell's diverticulum, is an uncommon, congenital, aortic arch anomaly. Surgery for a diverticulum is challenging, and several surgical strategies have been reported. Here, we present the case of an asymptomatic 57-year-old man who was referred to our hospital. Computed tomography revealed right aortic arch and aortic diverticulum, and he underwent distal limited open stenting under hypothermic circulatory arrest with selective cerebral perfusion via median sternotomy. The postoperative course was uneventful. Thus, this report shows that our procedure is useful and safe for treating aortic diverticulum.
