The Association between the Timing of Shunt Placement and Shunt Infection in Hydrocephalus Associated with Myelomeningocele

Özet

AIM: To determine whether the timing of shunt placement affects shunt infection rate in hydrocephalus associated withmyelomeningocele (MMC).MATERIAL and METHODS: The cases of 67 consecutive patients who underwent MMC repair and ventriculoperitoneal (VP)shunt placement between 2010 and 2017 were analyzed, retrospectively. Shunt infection rates were compared for three differentapproaches: simultaneous shunting (MMC repair and shunting in the same session; n=22), early shunting (shunting in the first weekafter MMC repair; n=21), and delayed shunting (shunting in the second week after MMC repair; n=24).RESULTS: Three patients in the simultaneous shunting group (13.6%) and two patients in the early shunting group (9.5%) developedshunt infection, whereas no such infections occurred in the delayed shunting group (p>0.05).CONCLUSION: While the shunt infection rates for the simultaneous, early and delayed shunting groups were not significant, it is ofinterest that no shunt infections occurred in the delayed shunting group. Investigation with a larger number of patients is warrantedto assess whether delayed shunting might reduce the risk of shunt infection.
