Abstract

The vein of Galen aneurysm is a rare vascular malformation but it can be detected by using conventional ultrasonography and diagnosed by using power Doppler ultrasonography. The prognosis of the vein of Galen aneurysm depends on congestive heart failure caused by cerebral shunt. Embolization at proper times can provide good outcome. We report a case of spontaneous delivery at 41 weeks of gestation by a 35-year-old woman presenting with a fetal vein of Galen aneurysm is described. The vein of Galen aneurysm was prenatally diagnosed by power Doppler ultrasonography and treated postnatally by embolization. This case is a report of successful prenatal diagnosis and postnatal management of the vein of Galen aneurysm.
