Treatment of Galen Vein Arteriovenous Malformation with Gamma Knife Surgery.

The vein of Galen arteriovenous malformation is a rare abnormality of the fetal cerebral vascular system. It is caused by the persistence of a cerebral arteriovenous fistula of the median prosencephalic vein. Due to the high mortality rate of the surgical option in its treatment, the approach with embolization and radiosurgery combinations continues to be popular. We present a 3-year-old child patient who was accidentally detected by vein of Galen malformations during a screening for headache complaints with known heart disease. In the treatment of this patient, we performed radiosurgery therapy alone, rather than a combination. Our case is the third case of a and the youngest example child who was treated with only radiosurgery without embolization. Gamma knife therapy, which is a more convenient and effective treatment plan, is a method that can be safely used instead of open surgery with a high mortality rate.
