Vein of Galen Malformation

Vein of Galen Malformation

The vein of Galen malformation is a rare, congenital blood vessel malformation in the brain that develops prenatally. It is an abnormal connection between the arteries and veins in the brain. This malformation develops between the sixth and eleventh weeks in the womb. The vein of Galen malformation is the most common arteriovenous malformation in fetuses.

Vein of Galen Malformation Symptoms

The vein of Galen malformation is usually symptomatic in newborns and may present symptoms in early childhood, but it’s less common. Newborns with this malformation typically show signs and symptoms of:

  • Congestive heart failure
  • Cyanosis
  • Tachypnea

Newborns that are symptomatic often require ventilator support with aggressive management to prevent heart failure. Early childhood symptoms include:

  • Cardiac failure
  • Convulsive seizures
  • Headaches
  • Hydrocephalus

In addition, large head circumference, prominent scalp veins and drooping eyes may be noted upon examination.
