In Brazil, the exact epidemiology of aneurysmal SAH is unknown. The most common presenting symptom is headache, usually described as the worst headache ever felt. Head computed tomography, when performed within six hours of the ictus, has a sensitivity of nearly 100%. It is important to classify the hemorrhage based on clinical and imaging features as a way to standardize communication. Classification also has prognostic value. In order to prevent rebleeding, there still is controversy regarding the ideal blood pressure levels and the use of antifibrinolytic therapy. The importance of definitely securing the aneurysm by endovascular coiling or surgical clipping cannot be overemphasized. Hydrocephalus, seizures, and intracranial pressure should also be managed. Delayed cerebral ischemia is a severe complication that should be prevented and treated aggressively. Systemic complications including cardiac and pulmonary issues, sodium abnormalities, fever, and thromboembolism frequently happen and may have na impact upon prognosis, requiring proper management.<\/jats:p>","DOI":"10.1590\/0004-282x20190112","type":"journal-article","created":{"date-parts":[[2019,12,6]],"date-time":"2019-12-06T14:16:04Z","timestamp":1575641764000},"page":"806-814","source":"Crossref","is-referenced-by-count":66,"title":["Aneurysmal subarachnoid hemorrhage: current concepts and updates"],"prefix":"10.1590","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5667-6523","authenticated-orcid":false,"given":"Carolina","family":"Rouanet","sequence":"first","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3247-3123","authenticated-orcid":false,"given":"Gisele Sampaio","family":"Silva","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2019,11]]},"reference":[{"issue":"6","key":"ref1","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.1161\/STR.0b013e3182587839","article-title":"Guidelines for the management of aneurysmal subarachnoid hemorrhage: a guideline for healthcare professionals from the American Heart Association\/American Stroke Association","volume":"43","author":"Connolly Jr ES","year":"2012","journal-title":"Stroke."},{"issue":"7","key":"ref2","doi-asserted-by":"crossref","first-page":"635","DOI":"10.1016\/S1474-4422(09)70126-7","article-title":"Changes in case fatality of aneurysmal subarachnoid haemorrhage over time, according to age, sex, and region: a meta-analysis","volume":"8","author":"Nieuwkamp DJ","year":"2009","journal-title":"Lancet Neurol."},{"issue":"5 NeurocriticalCare","key":"ref3","first-page":"1263","article-title":"Suarez.
