We herein describe a case of symptomatic improvement and diverticulum shrinkage that lasted 24 months after chimney thoracic endovascular aortic repair (TEVAR) for a Kommerell’s diverticulum (KD). A 61-year-old man presented with dysphagia lusoria due to a KD involving an aberrant right subclavian artery with a left-sided aortic arch. The patient underwent TEVAR and right subclavian artery coil embolization. His dominant left vertebral artery was transplanted for the left common carotid artery, and the left subclavian artery was stented (chimney technique). The preoperative diameter of the KD was 43.5 mm, and the distance to the opposite aortic wall was 54.5 mm. The postoperative diameter of the KD was 33.0 mm. The patient developed no spinal cord ischemia or right arm ischemia postoperatively. His symptoms of dysphagia and right arm claudication improved throughout the 1-year follow-up period. At the 24-month follow-up assessment, the patient had no symptoms and the size of the KD had not changed.
