Sequential measurements of ventricular sizes and Doppler variables of anterior cerebral artery (ACA) by duplex color ultrasound were performed on 14 ventriculomegalic infants (mean age: 3.4 months): 9 were postmeningitic, 3 posthemorrhagic, and 2 congenital. According to changes of the frontal horn radius (FHR) after shunts, the FHR was decreased > 30% (n = 9) in group I and ≤10% (n = 5) in group II. Before shunting, Pourcelot index (PI) in group I was greater than in group II (P<0.01), but FHR in group II was higher than in group I (P<0.01). The intracranial pressure did not vary between groups. Serial preshunt examinations showed a significant correlation between the degree of cerebrovascular resistance and the degree of ventricular dilation only in group I. After surgery, significant changes of end-diastolic velocity, the area under the velocity curve, and PI were found only in group I. The reservoir pumping test performed on 2 cases of recurrent ventriculomegaly in group I and 3 cases in group II Showed a decreased PI only in group I, in which the outcome was better. PI is useful in differentiating between hydrocephalic and atrophic ventriculomegaly. These data suggest that a ventriculomegalic infant with an unelevated PI value hardly benefits from a ventricular shunt.
