Neuro-endoscopic treatment for intraventricular cysts in children

Abstract

Objective To study the technical key points and effects of neuro-endoscopic treatment for intravcntricular cysts in children, and to analyze the features of velocity and flux of cerebrospinal fluid in patients of intraventricular cysts. Method Cine MRI was used to analyze the velocity and flux of eerebrospinal fluid. Among all the cases,there were 8 lateral ventricles cysts,2 third ventricle cysts,4 fourth ventricle cysts, 2 suprasellar araehnoid cysts and 1 quadrigeminal cistern arachnoid cyst. The neuro-endoscopic operation was performed to all kinds of intraventricular cysts in order to study the indication, optimal process and clinical effects. Results The CSF dynamic states were improved in all patients. It was found that the CSF passed through the stoma after ETV in all patients. The contraction of cyst was found in 14 cases, and there was no notable change in 3 cases. The total effective rate was 82. 4%. There was no surgery -related serious complication. The cyst enlargement or stoma obstruction was not found in all patients after 3 -19 months follow-up period. Conclusions Cine MRI and radionuclide cisternography are helpful to understand the CSF dynamic states in children with intraventricular cysts and they are important references for surgery and determination of prognosis. Neuronavigated endoscopic surgery may be more precise and safe. Post-operative lumbar puncture is helpful to reconstruct normal CSF circulation and improve the prognosis.
