Review Case ReportsScalp necrosis overlying a ventriculoperitoneal shunt: a case report and literature review.
The use of ventriculoperitoneal (VP) shunts has become ubiquitous in neurosurgery for the treatment of hydrocephalus. VP shunts work by creating a conduit for cerebrospinal fluid (CSF) to flow from the cerebral ventricles to the peritoneum and thus relieving pressure. Although typically safe, VP shunt complications are extremely common, occurring in up to 29% of adult cases and approximately half of pediatric cases. These complications may require patients to undergo several revisions throughout their lifetime Purpose: We describe a man who developed scalp necrosis overlying his VP shunt. We also summarize the potential complications of VP shunts. We discuss the presentation and pathogenesis of scalp necrosis in these patients. ⋯ VP shunts are devices that are frequently used for reducing intracranial pressure associated with hydrocephalus. The insertion of the shunt beneath the scalp sets the stage for potential pressure-induced scalp necrosis. The early recognition and diagnosis of VP shunt-induced scalp necrosis is essential to prevent infections and future complications.
