A retrospective chart review was performed on 54 patients who had undergone
endoscopic III ventriculostomy (E3V) in the past 6 years. Patient charts w
ere reviewed to establish age at the time of operation, sex, preoperative d
iagnosis, preoperative shunt procedures, success or failure of the E3V, dur
ation of success, and complications. Success of an E3V was determined by th
e resolution of preoperative symptoms and avoidance of a CSF shunt. The mos
t recent clinic visit with adequate documentation of signs and symptoms of
hydrocephalus was used as the last date of follow-up. The overall success r
ate was 74%. Children over the age of 3 years with an acquired CSF obstruct
ion had a significantly greater probability of successful treatment (P=0.05
). Younger children, especially those with hydrocephalus attributable to ob
struction of the arachnoid villi, as in intraventricular hemorrhage (IVH),
were less likely to benefit from E3V.
