Coil occlusion of patent ductus arteriosus associated with right aortic arch

Two children with patent ductus arteriosus and associated right aortic arch underwent successful transcatheter coil occlusion. Recognition of ductal anatomy and ensuring that no symptomatic vascular ring is present are important prior to embarking on ductal occlusion. It is concluded that coil occlusion of patent ductus arteriosus in association with right aortic arch is feasible, safe, and effective.
