Treatment of chronic subdural haematoma.

A further rise in chronic subdural haematoma (CSDH) prevalence is expected with an ageing population, and evidence-based guidelines are needed to direct treatment, while creating a platform for research. The Danish Chronic Subdural Hematoma Study (DACSUHS) has implemented the first Danish national CSDH guidelines in 2018 and have standardised CSDH management on a national level. Based on CSDH literature published between 2016 and 2022, these guidelines were updated in 2022. The updated guidelines are presented in this review.
