The case-fatality after aSAH is approximately 40% and those who survive often have functional, cognitive or emotional sequelae. We prepared guidelines according to Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology, using data from meta-analyses, randomised trials, prospective observational and case\u2013control studies, prospective registries with external validation and single-arm cohort studies with &amp;gt;\u200950 patients with aSAH. Based on high levels of evidence, we recommend oral administration of nimodipine and regular coiling over clipping if both aneurysm treatment options are equally suitable in patients who are in good clinical condition, and recommend against the routine use of antifibrinolytic drugs prior to aneurysm treatment and against the use of tirilazad, statins, magnesium sulphate or endothelin receptor antagonists. Because of lower levels of evidence, no evidence-based recommendations can be made for the prophylactic use of antiplatelet drugs or external lumbar drainage, hypertension induction, treatment of the ruptured aneurysm with endovascular devices other than coils or endovascular treatment of vasospasm. We formulated 37 expert-consensus statements, which include, among others, the suggestions to treat aSAH patients in a dedicated neuro-ICU or high care unit in a centre that treats at least 70 patients with aSAH per year or at least 35 patients with aSAH per year in geographically remote areas, and to treat the ruptured aneurysm within 24\u00a0h after ictus provided that the most dedicated team of experts is available. These guidelines present up-to-date recommendations and expert-consensus statements on key aspects in the management of aSAH patients.<\/jats:p>","DOI":"10.1093\/esj\/aakag043","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T13:46:27Z","timestamp":1778161587000},"source":"Crossref","is-referenced-by-count":12,"title":["European
