Abstract

The authors report on 125 patients who underwent endoscopic third ventriculostomy for obstructive hydrocephalus in three Italian Neurosurgical Centers. The series includes 77 cases of primary aqueductal stenosis, 33 with triventricular hydrocephalus due to external tumor compression, and 15 with tetraventricular hydrocephalus. The operations were carried out mainly under general anesthesia, using a flexible endoscope. Decrease of size of the third ventricle and the presence of a signal void at the level of the fenestration are the main postoperative MRI findings. Signs of intracranial hypertension, increased head circumference and Parinaud syndrome respond more frequently to the endoscopic treatment. The overall rate of good results (shunt-independent patients) in this series is 86.4%; primary aqueductal stenosis (93.5%) and triventricular hydrocephalus due to external compression (84.8%) are associated to the higher rate of good postoperative results than tetraventricular hydrocephalus (53.3%). Because of the very low invasivity of this technique, the absence of postoperative mortality and the scarce and usually transient postoperative complications, the authors advise to enlarge the indications for endoscopic third ventriculostomy to all patients with obstructive hydrocephalus when the third ventricle is large enough and there are no alterations of the CSF resorption.
