• vascular tumors
  • congenital hemangioma
• vascular malformations
  • simple:
    • nevus flammeus
    • nevus simplex
    • cystic hygroma
    • Vein of Galen aneurysmal malformation
  • combined
  • of major named vessels
    • congenital cardiac abnormalities
    • double aortic arch
    • left-sided superior vena cava
    • duplication of inferior vena cava
  • associated with other anomalies
    • Klippel-Trenaunay syndrome
