Chronic Subdural Haematoma

Using a closed drainage system after burr-hole evacuation reduces recurrence compared with no drain. Traditional outcome measures for chronic subdural haematoma miss patient-centred burdens such as prolonged hospitalization and repeated readmissions. Chronic subdural haematoma is a common neurosurgical condition involving liquefied blood between the dura mater and arachnoid layers. There is no international consensus on optimal drain location, duration, or active versus passive drainage for CSDH. CSDH incidence is increasing mainly because populations are ageing. Danish CSDH surgery uses a standardized protocol based on a single burr hole, irrigation, and 24-hour passive subdural drainage. Chronic subdural haematoma is an increasing neurosurgical burden, especially among elderly patients. Postoperative recurrence after burr-hole drainage occurs in about 12.8% of cases and may require reoperation. Demographic ageing and increased antithrombotic medication use are driving the rise in CSDH cases. Surgical treatment for chronic subdural haematoma usually evacuates blood to relieve pressure on the brain. Burr-hole drainage is a standard approach for chronic subdural haematoma. Burr-hol…
