[Double aortic arch: clinical aspects, diagnosis and therapy in children and adults].

Double aortic arch is a rare vascular anomaly which usually causes tracheal and esophageal compression in the first few months of life. During the last 30 years, 7 children, 2 to 24 months old, and one 29-year-old woman with double aortic arches have been treatedatour institution. Symptoms, diagnosis and treatment of these patients were evaluated. Dyspnoe, stridor, recurrent pulmonary infections, feeding problems and failure to thrive were the leading symptoms. Despite typical symptoms from early childhood, the diagnosis was missed in our adult patient. Typical compression of the esophageus and the trachea was visualized by esophagography by 7 and bronchoscopy/-graphy by 6 patients. Angiography was performed in all children, whereas magnetic resonance angiography and computed tomography were done in the adult patient. Resection of the smaller aortic arch, left in 3 and right in 5, through a right or a left posterolateral thoracotomy was uncomplicated and fully resolved the symptoms in all patients. Typical symptoms in early childhood should lead to prompt diagnosis and surgical treatment of double aortic arch. Surgical resection of the smaller aortic arch should also be performed in oligosymptomatic patients to prevent complications later. Preoperative angiography can be replaced by the less invasive magnetic resonance imaging and computed tomography.
