A Comparative Study Endoscopic Endoscopic Third Ventriculostomy in the Treatment of Obstructive Hydrocephalus Secondary to Posterior Fossa Tumour

Abstract

Background: Hydrocephalus is a clinical condition characterized by increased amount of cerebrospinal fluid in the brain. It results in dilatation of ventricles, increase intracranial pressure, brain atrophy, neurological impairment and even death. The management of hydrocephalous needs diversion, either intracranial or extracranial. The traditional treatment for all kind of hydrocephalous has been the implantation of ventricular shunt system. Endoscopic third ventriculostomy has been accepted as the procedure of choice for the treatment of obstructed hydrocephalous in adults and children. Methods: In this study, a total of 94 patients diagnosed with posterior fossa tumor and obstructive hydrocephalus were selected in a consecutive manner from the outpatient department and subjected to ETV. Glasgow coma scale (GCS) at baseline & follow up were recorded to determine good or bad clinical outcome. Objective: To determine the outcome of Endoscopic Third Ventriculostomy in the treatment of Obstructive hydrocephalus secondary to Posterior fossa tumour in dhq hospital Mardan out of 94 patients. Results: The mean age of the patients was 10.82 + 4.49 years. Of the whole sample, we had 64.9% of males and 35.1% females. The mean GCS on baseline of our group of patients was 9.4 + 1.2 which was improved to 12.7 + 1.3 after Endoscopic third ventriculostomy. (p value 0.000). Good clinical outcome was observed in 71.3% of patients while bad clinical outcome in 28.7% of patients the mean age of the patients was 10.82 + 4.49 years. Of the whole sample, we had 64.9% of males and 35.1% females. The mean GCS on baseline of our group of patients was 9.4 + 1.2 which was improved to 12.7 + After Endoscopic third ventriculostomy. (p value 0.000). Good clinical outcome was observed in 71.3% of patients while bad clinical outcome in 28.7% of patients. Conclusions: Endoscopic third ventriculostomy is a preferred treatment for patients who had obstructive hydrocephalus due to posterior fossa t
