Journal of Cardiothoracic Surgery 2010 5 35 http content 5 1 35 JOURNAL OF CARDIOTHORACIC SURGERY CASE REPORT Open Access Surgical repair for aortic dissection accompanying a right-sided aortic arch Yukio Obitsu Nobusato Koizumi Toru Iwahashi Naozumi Saiki and Hiroshi Shigematsu Abstract Aortic anomaly in which a right-sided aortic arch associated with Kommerell s diverticulum and aberrant left subclavian artery is rare. The present report describes a patient with type-B aortic dissection accompanying aortic anomalies consisting of right-sided aortic arch and the left common carotid and left subclavian artery arising from Kommerell s diverticulum. As dissecting aortic aneurysm diameter increased rapidly Single-stage surgical repair of extensive thoracic aorta was performed through median sternotomy and right posterolateral fifth intercostal thoracotomy yielding favorable results. Our surgical procedures are discussed. Background Aortic anomalies in which a right-sided aortic arch is complicated by an aberrant left subclavian artery are rare with a reported incidence of of the population 1 . While many patients are asymptomatic surgery is indicated when accompanied by Kommerell s diverticulum aneurysm or vascular ring compression. We performed single-stage surgical repair of extensive thoracic aorta for a patient with aortic anomalies consisting of right-sided aortic arch the left common carotid and left subclavian artery arising from Kommerell s diverticulum and type B aortic dissection obtaining favorable results. Our surgical procedures are reported herein. Case presentation The patient was a 57-year-old man who had been diagnosed with right-sided aortic arch and Kommerell s diverticulum. Since he was asymptomatic at diagnosis he was being monitored. The patient developed type B acute aortic dissection DeBakey IIIa and the dissecting aortic aneurysm diameter rapidly increased. He was referred to our hospital 4 .
