Spontaneous subarachnoid haemorrhage - review
Sveinsson OA, Olafsson IH, Kjartansson O, Valdimarsson EM
Spontaneous subarachnoid hemorrhage is a bleeding in to the subarachnoid space without trauma. Aneurysms are the underlying cause in 80% of the
cases. Among other causes are: arteriovenous malformations, anticoagulation, vasculitis or brain tumor. Spontaneous subarachnoid hemorrhage is a
serious disease, where up to half of the patients die. Of those who survive, only half return to work and many have a reduced quality of life. To prevent
rebleeding the aneurysm is closed either with endovascular coiling or neurosurgical clipping.
Keywords: Spontaneous subarachnoid haemorrhage, rebleeding, vasospasm, hydroœphalus.
