Vein of Galen malformation

Vein of Galen malformation is a rare brain condition where abnormal blood vessels develop deep inside the brain, creating a tangled network. Instead of blood flowing normally through healthy vessels, it shunts directly into large veins, causing increased blood flow and pressure. This can lead to symptoms like a rapidly enlarging head in infants, headaches, seizures, or neurological issues. It results from abnormal blood vessel development before birth. Treatment often involves procedures to block or close the abnormal vessels, helping to reduce symptoms and prevent complications.
