Kommerell diverticulum (KD) is an aneurysm of the orifice of an aberrant subclavian artery (SCA) from the descending aorta or aortic arch. We have performed two-staged surgical strategy for the treatment of KD with right aortic arch. The first step was the bypass grafting between the left common carotid artery and the aberrant left SCA with occlusion of the distal side of KD with the plug. The second step was the descending aorta replacement through the right thoracotomy. Four patients underwent these operations. No hospital deaths or major complications were observed. All four patients were discharged and have been alive for 1–6 years without any health problems. Two of four patients had symptoms of dysphagia preoperatively, and it resolved postoperatively in both patients. No hoarseness occurred after surgery, and 1–6 years of CT observation showed no recanalization of the vascular plug.

Kommerell 憩室 (KD) 是来自降主动脉或主动脉弓的异常锁骨下动脉 (SCA) 开口的动脉瘤。我们采用两阶段手术策略治疗右主动脉弓 KD。第一步是在左侧颈总动脉和异常左侧 SCA 之间进行旁路移植术，并用栓塞阻塞 KD 的远端。第二步是通过右侧开胸进行降主动脉置换。四名患者接受了这些手术。未观察到医院死亡或重大并发症。所有四名患者均已出院，并且已经存活了 1-6 年，没有任何健康问题。四名患者中有两名在术前出现吞咽困难症状，两名患者术后均得到缓解。手术后没有声音嘶哑，
