Hemorragia subaracnoidea, revisión bibliográfica

Abstract

Cerebrovascular accidents frequently develop in the entire population, with a certain prevalence in the female sex and depending on certain risk factors that predispose to their development. Subarachnoid hemorrhage belongs to this group of pathologies, with a high incidence, especially in patients with a hereditary family history. Statistically, the number of deaths from ruptured aneurysms has increased progressively in the last 10 years. What is really worrisome is that the clinical picture of subarachnoid hemorrhage tends to confuse the doctor, presenting headache as the predominant symptom; however, because it is non-specific and not very sensitive, it masks the picture and confuses it with other less serious pathologies, which it facilitates the development of neurological sequelae and even death from reb leeding. The bibliography mentions a protocol of complementary examinations that must accompany patients who present sudden headache, to avoid false negatives and make an accurate diagnosis. Angiography has been classified as the gold standard for the diagnosis and localization of the aneurysm, however, since it is not very easily accessible due to cost, computed tomography without contrast is very helpful in deciding management, according to the scale of Fisher.
