Incidence of infection rate for shunt implantation: the zero % rate is always a myth

Abstract

Introduction Paediatric CSF shunt infection rate remains a well-known complication that is not only responsible of potentially severe sequels for patients but also for economical expenses. In that study, we questioned if it is possible to attain the zero percent rate of infection that should be the goal of every paediatric neurosurgeon. Methods We report our series of patients treated with a CSF device from January the first 2016 to December 31 2018. Results In all 147 patients treated for hydrocephalus, the follow-up was of at least of 2 years from the implantation. Antibiotic-coated tubes were always used with a differential pressure valve system. A total of 172 surgical procedures were performed for 147 patients. In the follow-up time period, 4 patients presented a post-operative infection (2.3%). Two infections appeared early after the surgical procedure one after 24 h and the other after 6 days; the other two infections were diagnosed after 53 days and the other after 66 days. The germs responsible of the infections were a Staphylococcus capitals, an Escherichia coli, a Klebsiella pneumonia, and a Staphylococcus aureus. Conclusions Shunts will always be implanted especially in new-borns and for particular aetiologies of hydrocephalus. To reduce the rate of infection, the best thing to do is to adopt adapted protocols. Our low incidence of infection rate for shunts represent a long history to research preventive factors that helped us to improve our results during the time.
