Surgical Management and follow-up of vascular rings.
Thirty patients with aortic arch anomalies resulting in tracheo-oesophageal compression were treated during the period 1966 through 1987. These anomalies are important causes of upper respiratory and oesophageal obstruction in babies and small children. Although symptoms started within the first months of life in most cases, only 15 underwent surgery before six months and a delay of more than one year occurred in 5. Diagnosis was established by chest roentgenogram, barium oesophagogram and angiography. Thirteen (43%) patients had a double aortic arch, 9 (30%) cases had aberrant right subclavian artery and 6 (20%) patients had right aortic arch with ductus or ligamentum arteriosum. One (3.5%) patient had pulmonary artery sling and 1 (3.5%) case had right aortic arch and ductus arteriosum and aberrant right subclavian artery. Associated malformations were seen in 8 (27%) cases, (4 ventricular septal defects, 1 atrial septal defect, 1 coarctation of the aorta, 1 hypoplasia of left pulmonary artery, 1 left diaphragmatic eventration). Basic surgical procedure includes exposure through a left thoracotomy, complete identification of the anomaly and division of the constricting ring. 85% of the patients are asymptomatic and minimal to moderate stridor persists among the remainder. Severe tracheomalacia was responsible for the only two deaths in the series.
