Objective: Endoscopic third ventriculostomy (ETV) for the treatment of hydrocephalus of different aetiologies is still controversial in children younger than two years of age. The success rate of ETV in this group of patients is analyzed in this study.

Methods: The series consisted of 21 patients treated with ETV. The mean age was 6.7 months, ranging from 9 days to 15 months (16 patients were younger than one year). The study included hydrocephalus due to idiopathic aqueductal stenosis (8), and other congenital anomalies (4), as well as posthemorrhagic (3), and tumour-related occlusive hydrocephalus (3). Two patients presented with shunt infection and one with a shunt failure. ETV was considered to be successful when shunting could be avoided.

Results: ETV was successful in 9 patients with a mean follow-up period of 26.2 months. The procedure was successful in 4 patients with idiopathic aqueductal stenosis, in 2 with other congenital anomalies, in 1 posthemorrhagic and in 2 with a tumour-related hydrocephalus. In 12 patients the ETV was unsuccessful after a mean follow up of 3.3 months. These patients required a shunt. Ten of them were less than one year old when ETV was performed. In 1 tumour-related hydrocephalus a shunt was inserted after a meningitis following tumour removal.

Conclusions: Our results show an overall success rate in 43% of the children treated with ETV. It had to be noticed that shunt implantation was mainly required in children less than a half year of age. The results support the necessity of prospective randomized trial concerning the efficacy of ETV versus shunts in this group of children.
