Abstract
This study compares the effect and rehabilitation prognosis of 6-month combined ventriculoperitoneal shunt (VPS) versus rehabilitation training alone in chronic normal-pressure hydrocephalus patients. Method: After suffering from aneurysmal subarachnoid hemorrhage, 39 subjects were diagnosed with chronic normal-pressure hydrocephalus because of clinical deterioration or nonimprovement of gait ataxia, cognitive disturbance, and/or urinary incontinence during rehabilitation. Twenty-four subjects underwent ventriculoperitoneal shunt (VPS) placement, while 15 subjects did not undergo the procedure. Results: Statistically significant increases in the Barthel Index (BI) were observed between the treatment and control groups 1 month (p < .05) and 6 months (p < .01) after VPS placement. Similar changes also were observed for the Mini-Mental State Examination (MMSE) at the 1-month (p < .01) and 6-month follow-up visits (p < .01). Significant differences in the change in MMSE and BI at admission, before VPS placement, and at 1 month and 6 months after VPS placement in the treatment group were demonstrated (p < .01). Conclusion: Chronic normal-pressure hydrocephalus after aneurysmal subarachnoid hemorrhage is an important issue to which clinicians should pay attention. It negatively influences the functional and behavioral outcome of rehabilitation but can be treated.
