Cerebral artery reverse flow as an indicator of critical intracranial hypertension in fetal intracranial hemorrhage: Case report.

Intracranial hemorrhage (ICH) is a rare serious fetal event. It manifests via non-specific sonographic findings such as: ventriculomegaly, increased periventricular echogenity, hyperechogenic ependyma and presence of avascular intracranial masses. Severe ICH causes an increase in fetal intracranial pressure, which can be quantified in utero by the presence of reverse flow in the middle cerebral artery (MCA-REDF).
