ABSTRACT

The goal of this work was to report on a series of preoperative endoscopic third ventriculostomy (ETV) performed for obstructive hydrocephalus due to posterior fossa tumors. Eight patients underwent preoperative ETV prior to tumor biopsy or removal for obstructive hydrocephalus related to posterior fossa tumors. All patients underwent surgery in two steps; ETV followed a week later by tumor resection. Clinical, radiological and outcome data were retrospectively reviewed. Eight patients (6 males, 2 females) aged between 8 and 45 years (mean age 24.62 years) suffering from obstructive hydrocephalus due to posterior fossa tumors had ETV prior to tumor removal or biopsy. Five patients were adults while 3 were under 18 years. All patients complained of headaches, seven presented with symptoms of raised intracranial pressure or visual disturbances and four had vomiting or cerebellar disturbance. Computed tomography scan was done in all patients and magnetic resonance imaging in five. Complete tumor removal was achieved in 4 cases and partial removal or biopsy in the remaining 4. ETV was successful in 7 (87.50%) cases but failed in one. Two patients experienced intraoperative transitory bradycardia. Two postoperative complications occurred (one meningitis and one CSF leak). No death related to procedures occurred. The histological diagnosis were as follows: ependymoma (3), medulloblastoma (3), astrocytoma grade II (1) and pineoblastoma (1). Hospital stay ranged from 9 to 21 days (mean, 12.71 days). Follow up range was 4 months to 78.4 months (0.33 to 6.53 years; mean, 46.11 months (3.84 years); median, 41.2 months (3.43 years).
