    Abstract:
    To better understand the clinical presentation and surgical management of children with aortic arch complex anomalies ("vascular rings"), a retrospective study was performed on patients who presented to Children's National Medical Center between the years 1969 and 1989. A total of 59 patients were identified ranging in age at admission from birth to 14 years, of whom 35 (59%) were male and 24 (41%) female. Patients were classified into four major subtypes based on their surgical anatomy, with 29 (49%) patients having right aortic arch and left ductus/ligamentum arteriosus, 21 (36%) double aortic arch, 6 (10%) anomalous left pulmonary artery, and 3 (5%) arch artery anomaly (no ring); 19 patients (32%) had associated cardiac defects. The mean (+/-SD) age at onset of symptoms was 4.6 +/- 14.0 months, and the age at surgical repair was 18 +/- 34 months. There were no intraoperative mortalities, but two late deaths occurred. Three (5%) patients had a surgical complication. In contrast to previous studies, the incidence of nonring lesions was lower and associated cardiac defects higher. Forty-nine percent of patients had symptoms present at birth, and patients with associated cardiac disease did not present earlier than those without. In patients with right aortic arch and left ductus/ligamentum arteriosus, few had an anomalous left subclavian artery. Finally, equal dominance of the arches was most frequent in patients with double aortic arch. Aortic arch complex anomalies present symptomatically in a variety of ways, and noninvasive methods are used to identify the specific lesion and associated cardiac defects. Surgical repair is associated with low or no mortality in patients with uncomplicated aortic arch complex anomalies.
