ObjectivesSubdural hematoma is one of complications of ventriculoperitoneal (VP) shunt for hydrocephalus. We observed many cases of subdural hematoma on early post-operative computed tomography scan performed after VP shunt. We analyzed clinical features and factors related occurrence of subdural hematoma after VP shunt.
Methods:From January 2009 to December 2011, 104 patients underwent shunt surgery by programmable valve for hydrocephalus. The demographic factors, preoperative medications, causes of hydrocephalus, radiologic features, and operative findings were reviewed. We divided patients into two groups: occurrence of subdural hematoma (Group A) and no evidence of subdural hematoma (Group
Results:Fifty-eight patients (55.8%) had a subdural hematoma after VP shunt. Mean setting pressure of valve was higher in group B compared to group A. A setting pressure is the only factor related to occurrence of subdural hematoma. Five patients in Group A (8.6%) had symptoms of subdural hematoma. Though subdural hematoma was absorbed spontaneously or by increasing of setting pressure of valve in majority of Group A, five patients underwent additional operation.
Conclusion:The setting pressure of valve was important to prevent and treat subdural hematoma after VP shunt for hydrocephalus.
