Predictors of favorable response to implanted of ventriculoperitoneal shunt in patients with idiopathic normal pressure hydrocephalus

Introduction: The indication of a ventriculoperitoneal shunt (VPS) is discussed in patients with idiopathic normal pressure hydrocephalus (iNPH), due to the heterogeneity of the response to treatment and the risks involved in neurosurgery. Objective: To search for clinical factors and complementary studies in order to determine predictors of a favorable response to the VPS placement in patients with iNPH. Methodology: A retrospective study of patients with probable iNPH (according to international guidelines) treated with VPS assisted in a neurological clinic from January 2014 to January 2017 was conducted. A univariate statistical analysis of the variables considered as possible prognostic factors was performed. Results: 58 patients were included. Women presented 3.68 times more chances of improvement after the VPS (p=0.019). Good response to the gait test was associated with better response to the VPS (p=0.024). Conclusions: Female sex and good response to the gait test could be considered as predictors of a favorable response to the VPS placement in patients with iNPH. A prospective study is necessary to achieve a homogeneous diagnostic evaluation and a more extensive longitudinal follow-up to evaluate the clinical evolution in this group of patients.
