右側大動脈弓に伴うKommerell憩室により食道狭窄症状を呈した1例

Surgical Repair of Kommerell’s Diverticulum with Right Sided Aortic Arch；Report of a Case

はじめに　右側大動脈弓に伴うKommerell憩室は比較的まれな疾患である．鎖骨下動脈起始異常を合併しないKommerell憩室により食道狭窄症状を呈した症例を経験したので報告する．

A 54-year-old woman was referred for assessment of dysphagia and extrinsic compression of the esophagus detected by upper gastrointestinal endoscopy. Computed tomography revealed the right-sided aortic arch with mirror image branching and Kommerell’s diverticulum. To relieve the esophageal compression, surgical intervention was indicated. Descending aortic replacement with a Dacron graft was performed through right thoracotomy under partial cardiopulmonary bypass. The patient was discharged without any complication, and her dysphagia disappeared.
