Prenatal diagnosis of the aneurysm of the vein of Galen by pulsed Doppler unit.

Aneurysm of the vein of Galen is a rare anomaly. In the severe type, the first clinical manifestation of this anomaly is heart failure after birth. Prenatal diagnosis is important in preventing heart failure during the postnatal period. Here, we report the prenatal diagnosis of a case of aneurysm of the vein of Galen in which we used a pulsed Doppler unit combined with a fetal electrocardiogram-phonocardiogram unit.
