Hemorragia subaracnóidea (HSA) é definida como o acúmulo de sangue no espaço entre a membrana aracnoide e a pia-máter ao redor do cérebro, denominado espaço subaracnoideo. A HSA se manifesta como disfunção neurológica aguda e frequentemente é um evento clínico devastador, com mortalidade substancial e alta morbidade entre os sobreviventes. A apresentação clássica frequentemente é uma cefaleia intensa de início súbito, tipicamente descrita como a "pior dor de cabeça da minha vida". A etiologia da HSA pode ser de natureza não traumática (cerca de 85% são secundárias a ruptura de aneurisma) ou traumática._x000D_ Esta categoria destina-se apenas a HSA não traumática. | |||

Subarachnoid hemorrhage (SAH) is defined as the accumulation of blood in the space between the arachnoid membrane and the pia mater around the brain, referred to as the subarachnoid space. SAH demonstrates as acute neurological dysfunction, and is often a devastating clinical event with substantial mortality and high morbidity among survivors. The classic presentation is often a sudden-onset, severe headache typically described as the "worst headache of my life".
