There were 15 girls and 11 boys in the series. The median age at the time of surgery was 7 years (range 7 months\u201317 years).

One bridging vein was sacrificed in 6 cases and 2 bridging veins were divided in 1 case, whereas in 3 cases there was sacrifice of a single deep cerebral vein. No patient developed radiographic evidence of venous infarction. Approach-related complications were low, and included 2 cases of transient homonymous hemianopia.
