Abstract :

Introduction: Endoscopic third ventriculostomy (ETV) is considered as a treatment of choice for obstructive hydrocephalus. It is done in hydrocephalus secondary to congenital aqueductal stenosis, third ventricle tumor, post infective, normal pressure hydrocephalus, multiloculated hydrocephalus, posterior fossa tumor and VP shunt dysfunction. Materials and methods: This is study of 77 patients with hydrocephalus who were treated with endoscopic third ventriculostomy during the period of 2014-2018 in our neurosurgery department. Following the procedure of endoscopic third ventriculostomy with right pre coronal burr hole and neuroendoscope technic, postoperative clinical assessment and radiological indices were followed up at 48 hours, 1 week, 4 weeks, 3 months after surgery. Results: The success rate in this study was 74.02%. The best effectiveness was observed in,Aqueductal stenosis (85.7%), ain tumors (77.7%), ventriculoperitoneal shunt, dysfunctions (75%), post TB meningitis hydrocephalus (66.7%). NPH had a success rate of 55.5%.The mean time for clinical and radiological improvement were 49.7 hours and 2.57 weeks. Conclusion: Endoscopic Third Ventriculostomy(ETV) is a very safe and effective procedure and is a useful alternative to ventriculoperitoneal shunt.Shunt related complications can effectively be avoided. Careful preoperative evaluation and proper selection of cases results in a good success rate
