[Preliminary results of the treatment of occlusive hydrocephalus in children by endoscopic techniques]

The group of 20 patients with the preliminary diagnosis of occlusive hydrocephalus were treated by neuroendoscopic technique. Ten ventriculocystocisternostomies in cases with third ventricle arachnoid cysts accompanied by hydrocephalus, 9 ventriculostomies, and 1 ventriculostomy with fenestration of posterior fossa cystic lesion were performed. It was proven that the neuroendoscopic procedures were effective in 17 cases (85%) in the 10 months mean follow-up period of the study group. With no mortality, transient surgical complications were observed in 5 cases (25%). In 3 cases, inefficacy of the method was caused by false preoperative evaluation, and inappropriate surgical technique.
