[Congenital vascular rings in children].

Two children with symptoms of dysphagia, dyspnoea and chronic pulmonary infections secondary to anomalies of the aortic arch are presented. Diagnostic procedures included oesophagography and aortic arch angiography. These showed a double aortic arch in the first child and an aberrant right subclavian artery in the second one, leading to compression of both trachea and oesophagus. Both children underwent surgery: in the first child the atretic anterior arch and the left ligamentum arteriosum were divided; in the second child the aberrant right subclavian artery was divided at its origin from the descending aorta and connected to the ascending aorta. Follow-up examinations showed a complete recovery of both patients.
