Keywords:
Incidence, Infection, Ventriculoperitoneal shunting, Hydrocephalus, Coagulase negative staphylococciAbstract
Objective: To determine about the incidence of infection and causative organisms in patients with Ventriculoperitoneal shunting for hydrocephalus.
Materials and Methods: This retrospective observational study was carried out in the Department of Neurosurgery Lady Reading Hospital Peshawar, from Jan 2012 to Dec 2013 (one year). The medical record of all cases operated in last one year was checked from record room. Documentation was done according to Performa designed indicating age, sex, clinical features and type of microorganism. All patients of either sex and age with Previous Ventriculoperitoneal shunt surgery and Signs and symptoms suggestive of shunt infection were included in the study. While patients of previous Ventriculoperitoneal shunt with no signs and symptoms were excluded from the study. All the data were analyzed by SPSS 20 and results were represented in the form of graphs / tables.
Results: Total 82 patients were included in the study in which males were 50 (60.97%) and females were 32 (39.02%). All the patients were in the age range of 6 months to 75 years having mean age of 37.75 years ± 5 SD. 58 (70.73%) were in pediatric age group and 24 (29.26%) were adults. Regarding etiology congenital acquiductal stenosis was the leading cause in children’s having 22/58 (37.93%) and CNS tumors were the most common cause in adults having 10/24 (41.66%). Fever and vomiting were the most common mode of presentation with 66 (80%) cases. overall incidence of shunt infection was 12 (14.63%) in which the most common microorganism was coagulase negative staphylococci having 6/12 (50%) cases.
Conclusion: Shunt infection most commonly occur in children’s and coagulase negative staphylococci is the most common causative organism.
