 Demographic and outcome data after endoscopic third ventriculostomy or shunt surgery in 29 patients with non-communicating hydrocephalus and in 26 patients with normal pressure hydrocephalus

TypeAge (years)SexAetiologyPsychometric indexWakefulness indexGait indexBalance indexOverall improvement (MoD)
The aetiology of the non-communicating patients was classified as aqueductal stenosis, fourth ventricle outflow blockage, and foramen of Monro stenosis. The aetiology of the NPH patients was classified as idiopathic, subarachnoid haemorrhage, post-traumatic, or postoperative after tumour surgery. The clinical outcome after surgery is reported as scores on psychometric, wakefulness, gait, and balance indices. The overall postoperative improvement is expressed as the mean of the differences between preoperative and postoperative scores on the four indices.
AS, aqueductal stenosis; FMS, foramen of Monro stenosis; FVOB, fourth ventricle outflow blockage; INPH, idiopathic normal pressure hydrocephalus; non-comm, non-communicating; MoD, mean of differences; NPH, normal pressure hydrocephalus; SAH, subarachnoid haemorrhage.
