Ischemic complications of ruptured intracranial aneurysms

Eighty patients are reported with ischaemic complications developing during subarachnoideal haemorrhage due to aneurysm rupture. Ischaemic complications developed in 12.82% of cases in the whole group of subarachnoideal haemorrhages caused by aneurysm rupture. The causes of ischaemia were: closure or stenosis of the afferent artery during the operation, arterial spasm, thrombosis at the site of the aneurysm and brain oedema. Ischaemia during intracranial aneurysm rupture caused in most cases pale infarcts. Ischaemic complications of aneurysm rupture had a serious prognosis, nearly half the patients with this complication died.
