Sammanfattning
Chronic subdural haematoma (CSDH) is a collection of liquefied blood between the dura mater and the arachnoid layer of the brain. The incidence of CSDH increases with age and with an ageing population, and a rise in CSDH prevalence is anticipated. The Danish Chronic Subdural Hematoma Study was created on behest of the four neurosurgical departments in order to standardise treatment, research and development as well as creating the first Danish national guidelines in CSDH management. These guidelines are presented in this review.
