Neuroendoscope by endoscopic third ventriculostomy (ETV) and biopsy for treatment of the tumors in the posterior part of the third ventricle combined with obstructive hydrocephalus

Objective To explore the methods of treatment and curative effects of the tumors in the posterior part of the third ventricle combined with obstructive hydrocephalusunder neuroendoscopeby ETV and biopsy.Methods The clinical data and imaging findings of 22 patients with the tumors in the posterior part of the third ventricle combined with obstructive hydrocephalus by ETV and biopsy were retrospectively followed and analyzed;and related literatures were reviewed.Results All patients were performed by ETV.The clinical symptoms improved obviously after the surgery,and no significant tumor growth except two cases,and there is no dead case.Conclusion ETV and biopsy is an effective and reliable alternative treatment for the tumors in the posterior part of the third ventricle combined with obstructive hydrocephalus.Neuroendocopic procedures offer the opportunity to combine tumors biopsy and treatment of hydrocephalus.
