RESUMO
AIMS: The present study aimed to evaluate the clinical usefulness of endoscopic treatment of suprasellar arachnoid cysts indenting the third ventricle with obstructive hydrocephalus and discuss the clinical features and outcomes of thirteen children treated at our institution. METHOD: We treated thirteen pediatric cases of suprasellar arachnoid cysts indenting the third ventricle with obstructive hydrocephalus between January 2012 and September 2018. Five female and eight male patients were enrolled in the study. The patients had increased intracranial pressure symptoms due to hydrocephaly. Endoscopic treatment was performed in all cases. RESULTS: The patients were followed-up for an average of 36.8 months. The postoperative intracranial pressure findings improved. There was a reduction in the size of the cyst and ventricles and enlargement of the cortical sulci. One patient suffered transient oculomotor nerve deficit. No further surgical interventions, such as shunt placement, were required during the follow-up period. The head circumference of two of the patients with macrocephaly were stable during the follow-up. There were no postoperative recurrences detected. CONCLUSIONS: Endoscopic cyst fenestration and third ventriculostomy are less invasive, safer, and more effective ways to treat suprasellar arachnoid cysts indenting the third ventricle with obstructive hydrocephalus in children with hydrocephaly.
