Chronic subdural hematoma treatment with adjustment of programmable valve in idiopathic normal pressure hydrocephalus patient: a case report

Chronic subdural hematoma (CSDH) is a common entity in daily neurosurgical practice. It is considered a benign condition. Idiopathic normal pressure hydrocephalus (INPH) is characterized by gait disturbance, dementia and/or urinary incontinence added to dilation of ventricular system due to disturbance of cerebrospinal fluid (CSF) circulation with normal CSF pressure. We describe an experience of a conservative treatment of subdural hematoma based in the physiopathology and ability to control the pressure in programmable valves. The adjustment of programmable valves in the treatment of INPH allow us the therapeutic control of hydrocephalus and an important tool to manage complications, especially overshunting and undershunting.
