    Abstract:
    Our intention was to compare the clinical outcome after surgical treatment of chronic hydrocephalus between patients who were subjected to neuroendoscopic third ventriculostomy and patients who underwent shunt implantation. At the Department of Neurosurgery of the Research Institute of Polish Mothers' Memorial Hospital from 1999 to 2001, 29 children, of an average age of 7 years (+/-7.1 years SD), underwent successful neuroendoscopic procedures, and from 1992 to 1994, 59 children, of an average age of 2 months (+/-1.9 months SD), underwent shunt implantation. The size of the ventricular system was described by the Frontal Horn Index and its change after operative procedures by the ratio of the final to the primary Frontal Horn Index. Head circumference was measured in percentiles according to the Kurniewicz-Witczakowa chart for Polish children. The reduction in head circumference after a neuroendoscopic procedure was, on average, significantly less than after a shunt implantation (0.39 percentiles +/-29.6 SD vs 17.93 percentiles +/-19.93 SD). Concerning the change in ventricular size after a neuroendoscopic procedure, it was noticed that the average ratio of the final to the primary Frontal Horn Index was 0.9. Meanwhile, the same parameter after a shunt implantation was 0.55. Based on the values of the Frontal Horn Indexes, it was observed that the ventricular system in infants after neuroendoscopic procedures was significantly larger than in other age groups (0.7 vs 0.5). After successful neuroendoscopic operations in a group of children suffering from Chiari II malformation, ventricular systems were slightly enlarged. The ratio of the final Frontal Index to the primary Frontal Horn Index was 1.31. In children suffering from chronic hydrocephalus, the average reduction in the size of the ventricular system and the rate of head circumference growth are lower after neuroendoscopic operations than after shunt implantations. Successful neuroendoscopic procedures are characterized by, on average, a higher rate of head circumference growth in infants than in neonates. In addition, the rate of head circumference growth after successful neuroendoscopic procedures could be higher than before the operation, which is clearly visible in children suffering from Chiari II malformation, but it does not mean a constant increase of that parameter during the postoperative period.
