BackgroundVentriculoperitoneal (VP) shunt exposure is rare. Small series reporting on managing this complication mainly focus on the pediatric population, where wound breaks over cerebrospinal fluid (CSF) chambers are observed most frequently. However, case series on adult patients are missing.MethodsBetween June 2004 and December 2019, 18 patients underwent VP shunt revision due to implant exposure. Pertinent data were retrospectively collected from the hospital database. Their full clinical history, laboratory values, neuroradiological imaging, pretreatment CSF characteristics, photographic and video material, and surgery types were reviewed.ResultsThe ventricular catheter was exposed in 8 patients (the frontal region in 6 and the occipital region in 2), the valve chamber at the retroauricular region in 6, the shunt tube in 7 (at the neck in 4, the supraclavicular region in 2, and the abdominal incision in 1). Multiple exposure sites were found in 2 cases. Two patients with CSF infections benefitted from system removal and temporary external ventricular drainage until infection control was achieved. The remaining 16 patients underwent on-ward revision (wound curettage, skin mobilisation, and resuture over the exposed part of the shunt), which was effective in 14 patients, but further revision was required in 2 patients.ConclusionsWhile rare, VP shunt exposure is a serious complication. In our experience, a prompt and accurate on-ward revision could save the implant in most patients without CSF infections.Copyright © 2023 Elsevier Inc. All rights reserved.
