Long-term control of hydrocephalus via endoscopic third ventriculostomy in children with tectal plate gliomas.

摘要

OBJECTIVE: We report the control of hydrocephalus in children with presumed tectal plate gliomas by the use of endoscopic third ventriculostomy (ETV). METHODS: The hospital records, office charts, and imaging studies from children who underwent ETV at the Children's Hospital of Alabama were reviewed. Thirteen children with the diagnosis of tectal plate glioma and hydrocephalus were identified. ETV was the primary therapy instituted for all but one of these children. Successful treatment outcome was defined as shunt freedom, improvement in symptoms, and reduced ventricular size. RESULTS: Thirteen children underwent a total of 15 ETVs, and all children were shunt-free at their most recent follow-up examinations. One child underwent successful secondary ETV, one child underwent shunt removal concomitant with the initial ETV, and one child underwent shunt removal concomitant with secondary ETV. Symptoms and signs resolved in all patients. All postoperative cranial imaging studies revealed normal or reduced ventricular size as compared with preoperative cranial imaging scans. The median follow-up period was 31 months. CONCLUSION: In our surgical experience, ETV has been uniformly successful in the management of hydrocephalus caused by tectal plate gliomas in children. ETV should be considered the treatment of choice for hydrocephalus in pediatric patients with tectal plate gliomas.
