| Summary: | 【Abstract】Objective: The management of se-condary normal pressure hydrocephalus (sNPH) is
controversial. Many factors may affect the surgery effect.
The purpose of this study was to identify the possible fac-tors influencing prognosis and provide theoretical basis for
clinical treatment of sNPH.
Methods: A retrospective study was carried out to
investigate the results of 31 patients with sNPH who under-went ventriculoperitoneal shunt surgery from January 2007
to December 2011. We processed the potential influencing
factors by univariate analysis and the result further by mul-tivariate logistic regression analysis.
Results: Factors including age, disease duration and
Glasgow coma scale (GCS) score before surgery significantly
influenced the prognosis of sNPH (P<0.05). Further logistic
regression analysis showed that all the three factors are
independent influencing factors.
Conclusion: Age, disease duration and GCS score
before surgery have positive predictive value in estimating
favorable response to surgical treatment for sNPH.
