Lesión cerebral precoz en la hemorragia subaracnoídea aneurismática

Abstract

Aneurysmal subarachnoid hemorrhage (SAH), considered by many to be one of the most serious diseases of the central nervous system, remains a devastating condition. It is a disease that presents with complex consequences in intracranial pathophysiology, and that evolves from the moment the cerebral aneurysm ruptures, with multiple subsequent neurological and extra-neurological complications. In this review, an update is made of the main pathophysiological phenomena that occur in the first 72 hours of SAH evolution, known as Early Brain Injury (EBI), and the main diagnostic evaluations and therapeutic measures are outlined according to the evidence and recent literature.
