Controlateral epidural hematoma after VP shunt: A case report.

Cerebrospinal fluid over-drainage is a common complication of ventriculoperitoneal devices (Ventriculoperitoneal shunt). In terms of hemorrhage, subdural hematomas are usually more frequent lesions than epidural hematomas, which, more rarely, may also be seen after ventricular shunt procedures and may lead to rapid neurological decline and even death unless a surgical procedure can be promptly performed. In our study we report the case of a 5 years old boy with history of congenital obstructive hydrocephalus treated with a ventriculoperitoneal shunt insertion when he was 8 months old. The patient was admitted with sudden deterioration of level of consciousness secondary to tri-ventricular hydrocephalus. He underwent a shunt revision. Two weeks later, he developed a loss of consciousness with a large left extradural hematoma contralateral to the side of ventriculoperitoneal shunt. He underwent an evacuation of the hematoma with a good postoperative outcome. Epidural hematoma, especially controlateral to Ventriculoperitoneal shunt, is extremely rare. The pathophysiology and the possible use of a programmable valve to prevent these lesions are briefly discussed.
