Hemorrhage within the intracranial or spinal subarachnoid space, most often resulting from INTRACRANIAL ANEURYSM rupture or CRANIOCEREBRAL TRAUMA (see also SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurologic deficits, intraocular subhyaloid hemorrhages, and a reduced level of consciousness which may progress to coma or death. Spasm of intracranial arteries (see VASOSPASM, INTRACRANIAL) frequently accompanies this condition and may lead to BRAIN ISCHEMIA or CEREBRAL INFARCTION. (From N Engl J Med 1997 Jan 2;336 (1):28-40)

Vertebral Artery Dissection
- Dissection wall artery, leading to formation an aneurysm that occlude vessel. Thrombus give rise emboli. Cervical fractures or related NECK INJURIES and CRANIOCEREBRAL TRAUMA are commonly associated conditions, although this process may occur spontaneously. Ischemia, infarction, hemorrhage in the vascular distribution of affected vertebral artery complicate condition.
