Fetal heart rate tracing with congenital aneurysm of the great vein of Galen.
A fetal heart rate tracing that is notable for decreased short- and long-term variability is seen in association with normal umbilical cord blood gas values. A great vein of Galen aneurysm is diagnosed in the neonatal period. This case exemplifies a central nervous system disorder that is present before labor and is associated with normal oxygenation of the fetus and an abnormal fetal heart rate tracing. The causes of diminished fetal heart rate variability are discussed.
