Abstract | OBJECT: METHODS: The modified Bayley Scales of Infant Development (BSID-III) test was administered to 93 children with spina bifida who were 5-52 months of age. Fifty-five of these children had been treated by ETV/ CPC, 19 received ventriculoperitoneal (VP) shunts, and 19 had required no treatment for hydrocephalus. Raw scores were converted to scaled scores for comparison with age-corrected norms. Ventricular volume was assessed by frontal/occipital horn ratio (FOR) calculated from late postoperative CT scans. The mean values between and among groups of patients were compared using independent samples t-test and ANOVA. The comparison of mean values to population normal means was performed using the single-sample t-test. Linear regression analyses were performed using BSID scores as the dependent variables, with treatment group and ventricular size (FOR) as the independent variables. Probability values < 0.05 were considered significant. RESULTS: There was no significant difference in mean age at assessment among groups (p = 0.8). The mean scale scores for untreated patients were no different from normal (all p > 0.27) in all portions of the BSID (excluding gross motor), and were generally significantly better than those for both VP shunt-treated and ETV/ CPC groups. The ETV/ CPC-treated patients had nonsignificantly better mean scores than patients treated with VP shunts in all portions of the BSID (all p > 0.06), except receptive communication, which was significantly better for the ETV/ CPC group (p = 0.02). The mean FOR was similar among groups, with no significant difference between the untreated group and either the VP shunt or ETV/ CPC groups. The FOR did not correlate with performance. CONCLUSIONS: The ETV/ CPC and VP shunt groups had similar neurocognitive outcomes. Neurocognitive outcomes for infants not requiring treatment for hydrocephalus were normal and significantly better than in those requiring treatment. The mean ventricular volume was similar among all 3 groups, and significantly larger than normal. There was no association between FOR and performance. Stable mild-to-moderate ventriculomegaly alone should not trigger intervention in asymptomatic infants with spina bifida.
