Diagnosis of anomalous innominate artery syndrome by spiral CT with 3D reconstruction of the airway: report of one case.

Stridor in infants is a symptom that indicates partial obstruction of the large airways. Vascular rings are an unusual cause of tracheal compression which can induce stridor in infants and children. We report a 4-month-old boy with recurrent wheezing and stridor for 2 months. Spiral computed tomography (CT) and three-dimensional (3D) reconstruction aided in the diagnosis of external compression on the trachea by an innominate artery. Successful relief of the airway's obstruction was achieved by aortopexy. Three months after surgery, he was symptom free without any medication.
