[Prognosis after ruptured intracranial aneurysm in men and women]

Of 1076 patients with aneurysmal subarachnoid haemorrhage, 674 were females and 402 males. No significant differences between females and males were seen as regards age, clinical condition on admission, pre-existing arterial hypertension and number of rebleeds. Angiographically demonstrated vasospasm was seen with a significantly higher incidence in females, which may possibly explain a significantly poorer outcome in females compared to males, despite a much higher rate in females of internal carotid artery aneurysms which have a significantly better prognosis compared with aneurysms at other sites.
