Blood from an intraventricular hemorrhage (IVH) can collect in the basilar
cisterns and cause ventriculomegaly and eventual need for ventriculoperiton
eal (VP) shunt. We looked for sonographic evidence of subarachnoid hemorrha
ge (SAH) in three basal cisterns and in the Sylvian fissure of 82 infants w
ith IVH, 30 of whom had ventriculomegaly. We found that ultrasonographicall
y diagnosed SAH and measurement of ventricular blood volume predict ventric
ulomegaly and need for VP shunt. (C) 2000 Elsevier Science Inc. All rights
