Epidural Hematomas due to Occipital Artery Injury Following Ventriculoperitoneal Shunt and Extraventricular Drainage

ABSTRACT

Ventriculoperitoneal (VP) shunt is a common treatment for hydrocephalic patients. However, complications, such as shunt tube occlusion, infection, intracranial hemorrhage, seizure can occur. Of these, intracranial hemorrhage may occur due to intracranial vascular injury or a rapid decrease of intracranial pressure (ICP). Most of these hemorrhages are subdural hematomas (SDH) while a few are epidural hematomas (EDH). It is extremely rare for an intracranial hemorrhage to occur due to an extension of the bleeding from an injured extracranial vessel. We report two cases of EDH due to occipital artery injury following VP shunt and extraventricular drainage (EVD).
