Aneurysmal subarachnoid Hemorrhage (SAH) is one of the major intracranial calamities that an individual can suffer from and which the doctor may face. It is defined as the blood into the subarachnoid space, where cerebrospinal fluid (CSF) normally circulates, or when an intracranial hemorrhage extends to that space. The aneurysmal rupture leads the patient to a critical state, with a high probability of morbidity and mortality. The care and management of patients with subarachnoid hemorrhage is vital for satisfactory evolution, as is the multidisciplinary approach involving endovascular neurosurgeons and neurosurgeons with experience in microsurgical management of cerebral aneurysms.
