[Interruption of the left aortic arch with right descending thoracic aorta disclosed in adulthood]

Evaluation of hypertension, in a 30 years old man, revealed an interruption of a left aortic arch beyond the origin of the left subclavian artery, associated with a right descending thoracic artery. Surgical restoration of the continuity between the ascending aorta and the low descending aorta was successfully achieved by interposition of a graft. Survival in adulthood without bronchial compression, is explained by the absence of ventricular septal defect and patent ductus arteriosus.
