An 11-month old girl with a feeding difficulty and recurrent aspiration pneumonia received surgical correction of complete vascular ring, which was formed by right aortic arch, aberrant left subclavian artery(LSCA) originating from Kommerell's diverticulum(KD) and ligamentum arteriosum. Through left posterolateral thoracotomy, the ligamentum arteriosum was divided to relieve the tracheo-esophageal bundle. KD was separated from the right descending aorta, and the left subclavian artery was severed from KD at its origin and trasfered to the side wall of left common carotid artery. Postoperative course was uneventful, and the patient has been followed up with a clinical improvement.

A 53-year-old woman had right aortic arch, Kommerell’s diverticulum and aberrant left subclavian artery (LSA) without any compressive symptoms. Hybrid operation was performed. This consisted of LSA bypass using a 6 mm ringed Gore-Tex graft between the left common carotid artery and aberrant LSA via a left supraclavicular incision, and stent graft insertion into the aortic arch via the right femoral artery. Postoperative computed tomography as well as intraoperative angiography demonstrated successful occlusion of Kommerell’s diverticulum and bypass of the aberrant LSA. There were no complications related to the operation or the intervention.

Forty year old woman with dysphagia underwent surgical correction of complete vascular ring formed by right aortic arch, Kommerell's diverticulum and ligamentum arteriosum. Operation consisted of ligamentum division, reduction diverticuloplasty and posterior diverticulopexy via left posterolateral thoracotomy. Dysphagia was relieved postoperatively, and concentic narrowing of esophagus in the level of aortic arch disappeared on postoperative esophagography.

A 57-year-old man with numbness and paresthesia of left arm is presented. There was no pulse in the left arm was absent and his chest radiograph suggested right-sided aortic arch. The aortogram showed right-sided aortic arch with Kommerell's diverticulum. The proximal portion of left subclavian artery was totally occluded and blood was being supplied through vertebral arteries to distal subclavian artery. He underwent bypass grafting between both subclavian arteries by an expanded polytetrafluoroethylene graft. Because the size of Kommerell's diverticulum was small, it need to be observed closely.

Background: Vascular ring is a rare anomaly of the aortic arch. We did surgical repair procedures on 16 cases of vascular ring over the past 12 years. This article reviews our results. Material and Method: Between 1995 and 2007, 16 patients (5 with double aortic arch, 7 with right aortic arch-left ligamentum, 4 with pulmonary artery sling) underwent surgical repair. Mean age at the time of the operation were as follows: double aortic arch, $5.7{\pm}5.5$ years; right aortic arch-left ligamentum, $6.1{\pm}13.4$ years; pulmonary artery sling, $2.9{\pm}2.6$ years. Five patients (71%) with right aortic arch-left ligamentum had an associated Kommerell's diverticulum. Two patients (40%) with double aortic arch, 2 patients (28.6%) with right aortic arch-left ligament and 4 patients (100%) with pulmonary artery sling had associated airway stenosis. Cardiac anomalies were present in 8 of 16 patients. Result: There was no peri-operative or post-operative mortality. The mean hospital stay was $27.1{\pm}38.2$ days. None of our patients underwent reoperation. Conclusion: Vascular ring is rare, but, it needs surgical correction. It is important to suspect the diagnosis and to validate with echocardiography. Preoperative and postoperative computed tomography and bronchoscopy are useful to evaluate the airway and surrounding structures.
