Vasospasm and delayed cerebral ischaemia in patients with spontaneous subarachnoid haemorrhage (aneurysmal and pretruncal non-aneurysmal): a centre’s perspective

@#Spontaneous subarachnoid haemorrhage (SAH) is a significant cause of stroke and may lead to severe neurological deficit or death. It is also associated with high morbidity and mortality for patients despite optimal medical and surgical treatment. Based on the World Health Organization the annual incidence of spontaneous SAH varies in different regions of the world between 2.0-22.5 per 100,000 populations with Finland and Japan having the highest incidence and South and Central America with lowest incidence.1
