Causes and treatment of intracranial haemorrhage complicating shunting for paediatric hydrocephalus.
Intracranial haematomas are a well-known complication of shunting procedures for hydrocephalic patients. Most are subdural haematomas, and epidural haematomas are much less common in this setting. Their aetiology is thought to be due to an overdrainage of cerebrospinal fluid and a rapid lowering of intracranial pressure, leading to the development of these haematomas. Since the advent of modern neuroimaging techniques, prompt diagnosis of postshunting intracranial haematoma has been possible even in asymptomatic patients. The choice between surgical and nonsurgical management of postshunting intracranial haematoma is a difficult and controversial issue, especially in asymptomatic patients. Several therapeutic options have been proposed for the treatment of postshunting intracranial haematoma. Evacuation of the haematoma by conventional neurosurgical methods with the implantation of a higher pressure valve system is the most common option adopted. Intraventricular haemorrhage is occasionally reported, chiefly in children with hydrocephalus associated with vein of Galen malformation.
