INTRODUCTION AND OBJECTIVES: Aortic vascular rings can produce compression and obstruction in the airway and/or esophagus early surgical treatment in the first days or months of life. The reported incidence range between 0.3-0.6% with an 0.5% in our series. The following is a retrospective analysis with clinical, radiological and angiocardiographic study of the patients operated on in our service with the diagnosis of aortic vascular ring focused on the surgical results. METHODS: A total of 43 children with ages ranging between 21 days and 10 years (mean age 17 months) underwent surgical treatment for aortic vascular ring, during the period between january 68 and january 94. Clinically, 74% had stridor, 27.4% gastroesophageal reflux, 34% pulmonary infection, 14% respiratory insufficiency with mechanical ventilation, 12% heart failure, 9% dysphagia, 2% crisis of bronchospasm and 2% tracheomalacia that require tracheotomy prior to surgical correction. Diagnosis was made by esophagogram 86% of the cases. Aortography as the late diagnosis method or for election to surgical approach was made in 85% of the cases. In 42% were double aortic arch, 32% anomalous right subclavian artery and 25% right aortic arch with left ductal ligamentum. RESULTS: Reoperation was performed in 4 cases. Two early (1 case for hemorrhage, 1 case for phrenic paralysis requiring diaphragmatic plication), and two late reoperations (1 aortopexy, 1 tracheal termino-terminal anastomosis) at 2 and 13 months respectively. Hospital mortality was 1 case (2%) with 1 additional late death (2%). Follow-up was performed in the remaining 39 cases with a mean of 11 years (ranging between 1 and 25 years. Thirty seven of 41 patients alive asymptomatic (90%). CONCLUSIONS: Due to a low mortality rate (2.3%) not related with the age of the patient at the moment of the surgical procedure based in our experience, we conclude that it is very important to perform both, early diagnosis and surgical treatment in order to avoid the potential residual lesion on the airway caused by tracheo-broncho malacia, in order to avoid the deleterious effect on the results both at early and later follow-up.
