ABSTRACT

The subarachnoid hemorrhage occurs by a bleeding in sthe section that usually is occupied by cerebrospinal fluid, and its more frequent nontraumatic cause is the rupture of an aneurysm. It represents only 2 to 5% of the stroke, but is the cause of 27% deaths in the productive population under 65 years old. The physiopathology initiates with the presence of a hemorrhage concerning the subarachnoid space and of the cerebral parenchymal which pauses quickly. Then, it initiates the coagulation cascade activation and clot retraction; as well as the degeneration of blood cells in chemical components, principally the vasogenic brain edema which takes place at the clot and the white substance. The main symptoms of this problem are the sudden severe migraine (described like the worse headache of life), nauseous, vomits, meningismus, photophobia and an alteration of the state of consciousness. The diagnosis is made mostly by computed axial tomography and a lumbar puncture. Its treatment is both medical and neurosurgical and its future and present development records are stratified in different scales according to the initial neurological condition.
