Endoscopic third ventriculostomy for normal pressure hydrocephalus. (Abstract)*. Dissertation. São Paulo, 2002.
João Gualberto Souza Carvalho**
We retrospectively have analyzed the clinical and radiological data of 15 patients diagnosed with Normal Pressure Hydrocephalus (NPH). The patients were selected on clinical and CT/RM basis for endoscopic third ventriculostomy (ETV) instead of ventriculoperitoneal shunt (VPS). Their age ranged from 48 to 78 years and there had 10 males, 5 females.
Gait disturbance, mental deterioration and urinary incontinence where present in all but two patients. The 15 patients have undergone ETV as single and only treatment for their NPH. The follow-up was performed by an independent neurologist who evaluated the mental status pre and post op. The gait disturbance was evaluated by an independent physical therapist. The follow up ranged from 11 to 37 months. Two patients had surgical complications following ETV (intracerebral haematoma and cronic subdural haematoma) that were properly treated.
There was no mortality in this group. Vast majority of patient had other associated clinical disease, mainly high blood pressure, coronary heart disease and diabetes. 13 patients in this group showed improvements after the procedure, followed by later deterioration to pre-morbidus status. Two patients showed no improvement.
Key wordes: endoscopic third ventriculostomy, normal pressure hydrocephalus.
