  • Title: [Neuroendoscopic surgery for intra- and para-ventricular tumors:impacts on biopsy and hydrocephalus treatment].
    Author: Kurosaki K, Hayashi N, Hamada H, Nagai S, Endo S, Kuroda S.
    Journal: No Shinkei Geka; 2014 Mar; 42(3):205-11. PubMed ID: 24598869.
    Abstract:
    In this report, the authors retrospectively review and discuss their results for neuroendoscopic surgery for intra- and para-ventricular tumors. This study included 28 patients who were admitted to our hospital for intra- or para-ventricular tumors between January 2005 and March 2013. There were 17 males and 11 females, and their age varied widely from 1 to 75 years. Using a neuroendoscopic technique, tumor biopsy was attempted in all 28 patients. Biopsy was possible in 25 patients(89.3%)but not in the other 3(10.7%)because of hypervascularity or tumor bleeding. Of these 25 patients, pathological diagnosis was possible in 23(92%), but not in other 2(8%)because of incomplete sampling. In 18 of 28 patients, various forms of hydrocephalus were observed. Neuroendoscopic procedures were quite useful to improve cerebrospinal fluid dynamics in 13 of these patients, including endoscopic third ventriculostomy(ETV)in 9(except for 1 patient with ETV failure), septostomy with ventriculoperitoneal shunting(VPS)in 3, and cystostomy in 1. Simple VPS was performed in the other 4 patients. These results suggest that neuroendoscopic surgery is valuable as a minimally invasive procedure for pathological diagnosis and hydrocephalus treatments in patients with intra- and para-ventricular tumors. Further development of neuroendoscopic equipment is warranted to accurately diagnose tumors with hypervascularity and subependymal tumors.
