2026 European Guidelines for Management of Aneurysmal Subarachnoid Haemorrhage

The provided text outlines the 2026 clinical guidelines for managing aneurysmal subarachnoid haemorrhage (aSAH), a severe type of stroke caused by a ruptured brain aneurysm. Developed by several European medical societies, the document establishes standardized protocols to reduce the high rates of death and disability associated with this condition. The guidelines prioritize early intervention, specifically recommending that aneurysms be treated within 24 hours of the initial rupture. Endovascular coiling is generally favored over surgical clipping for patients in stable condition when both options are viable. Furthermore, the sources emphasize specialized care in high-volume neuro-ICUs and advocate for the use of oral nimodipine to prevent secondary brain damage. Conversely, the authors advise against the routine use of several common treatments, such as antifibrinolytic drugs and statins, due to a lack of proven benefit.
