title: [Vascular ring and pulmonary loop: experience with the surgical treatment].
abstract: Operation was carried out on 143 children (aged from 5 days to 16 years) for tracheobronchial obstruction caused by vascular rings. A double arch of the aorta was found in 50 patients, double arch of the aorta with atresia of the left arch--in 50 patients, right arch of the aorta with ligamentum arteriosum--in 30, left arch of the aorta with an aberrant right subclavian artery--in 10, and a pulmonary loop in 3 patients. Stridor was the main clinical manifestation of the vascular ring. The diagnosis was established by means of two-projection chest radiography and esophagography with a barium meal, bronchoscopy, and angiography. The surgical approach was gained through a posterolateral (left or right) thoracotomy. No deaths occurred during the operation. Two infants died in the postoperative period from a severe bacterial infection of the respiratory tract. On the basis of a rich clinical experience the authors came to the conclusion that the presence of a right aortic arch (except for cases with situs inversus) is always pathognomic because it either causes the appearance of a vascular ring without any intracardiac anomaly, or it may be combined with a congenital heart disease in which a vascular ring is usually not encountered (tetralogy of Fallot, truncus arteriosus communis, etc.). The authors never encountered atresia of a segment of the right aortic arch. The last-named was either patent or absent.
