Differential diagnosis of pediatric vascular rings and slings

• Left aortic arch with aberrant right subclavian artery
• Right aortic arch with aberrant left subclavian artery
• Right aortic arch without an aberrant vessel
• Double aortic arch
• Pulmonary sling
• Innominate artery compression

Approach to the differential diagnosis of vascular rings and slings:

• Cause of anterior esophageal indentation – pulmonary sling
• Causes of posterior esophageal indentaion – aberrant subclavian artery, double aortic arch
• Causes of anterior airway indentation – double aortic arch, innominate artery compression
• Cause of posterior airway indentation – pulmonary sling
