Abstract

Objective
Ventriculoperitoneal (VP) shunt has been used for the management of hydrocephalus. Subdural hematoma is occurred due to overdrainage of cerebrospinal fluid after VP shunt. We reviewed the result of hydrocephalus treated by VP shunt in geriatric patients.
Methods
From January 2009 to December 2014, VP shunt was done in 63 patients of hydrocephalus by programmable valve. We divided the patients into two groups according to evidence of subdural hematoma. The factors associated with occurrence of subdural hematoma were analyzed.
Results
Subdural hematoma was occurred in 32 patients (50.8%). The initial setting pressure of valve was a significant factor associated with occurrence of subdural hematoma. Subdural hematoma was treated by increasing of setting pressure in 27 patients and aspirated by operation in 3 patients. Subdural hematoma of the other 2 patients was absorbed spontaneously.
Conclusion
We need to carefully consider the initial setting pressure of programmable valve to avoid a complication of subdural hematoma.
