Abstract
Infection remains the most significant complication of ventriculoperitoneal shunt (VPS) surgery. The objective of this study was to investigate intracranial infections complicating VPS surgery in adults with hydrocephalus. Patients who underwent VPS surgery for hydrocephalus between 2000 and 2016 were included. Clinical data and follow-up evaluations were examined and analysed retrospectively. A total of 502 patients with hydrocephalus who underwent VPS surgery were included. They were followed up for at least 2 years. Twelve patients with incomplete data were excluded. Four hundred and ninety patients were included in the final analysis. Twenty-five cases of intracranial infection occurred, accounting for 5.1% of patients with VPS surgery. The mean age of the patients was 57.1 ± 10.1 years (range, 39-72 years). The incidence of intracranial infection in patients over 60 years of age was higher than that in patients under 60 years of age (P = .007). Age (P = .007), diabetes (P = .026), skin infection (P = .028), bed-ridden (P = .007), and modified operation (P = .011) were highly correlated with the incidence of intracranial infection. The findings of this retrospective study show that age, diabetes, skin infection, bed-ridden, and modified operation of hydrocephalus significantly and independently correlated with the incidence of infection. Prospective studies are needed to assess the relationship between the incidence of infection and risk factors in patients with hydrocephalus after VPS.
