Among people younger than 40 years,more men than women are likely to have subarachnoid hemorrhages (SAHs); among those older than 40 years,more women have SAHs.Hemorrhage from arteriovenous malformation rupture has a better chance of survival and is associated with an overall mortality rate of 10% to 15%.Ninety percent of aneurysms are congenital,the cause of which is unknown.The other 10% can be the result of traumatic injury (that stretches and tears the muscular middle layer of the arterial vessel)or infectious material.
