title: [Chronic wheezing child and type "D" double aortic arch: case report].
abstract: Right aortic arch with retroesophageal left innominate artery is an unusual pathology. The presence of patent ductus arteriosus, or left ductal ligament, does complete the vascular ring (Type "D" double aortic arch). In infants with dysphagia, stridor and/ or recurrent wheezing, presence of vascular rings may be suspected. In older patients this diagnosis is less common. Children in school age or older with risk factors, positive bronchodilator test and bad evolution, could have other unusual etiologies. We report an 8 year old patient with previous diagnosis of asthma with inadequate response to treatment in whom this non-frequent type of vascular ring was confirmed.
