The vein of Galen malformation is a midline intracranial arteriovenous fistula with aneurysmal dilatation of the vein of Galen. This abnormality, though rare, is associated with a bleak prognosis and significant mortality. However, significant advancements have been made in understanding the pathophysiology of this abnormality, and improvements in both interventional neuroradiologic embolization and microneurosurgical techniques have contributed to a better outcome. In neuroradiologic embolization, children are likely to become agitated and confused and thereby jeopardize the entire procedure. For this reason, this procedure is performed with the children under general anesthesia. We experienced a case of neuroradiologic embolization under general anesthesia with propofol. The patient was a 9- year-old boy who weighed 29 kg. He was healthy and had no other abnormalities in our preoperative evaluation. Throughout the entire procedure, especially before and after closure of the fistula, hemodynamic changes and unexpected events did not appear.
