My name is Gary Steinberg.
I'm the Lacroute-Hearst Professor and Chair of the Department of Neurosurgery at
Stanford University School of Medicine and
the founder and co-director of the Stanford stroke center.
I'm going to talk to you today about subarachnoid hemorrhage diagnosis and management.
0:18
As you can see, subarachnoid hemorrhage represents only about 10 percent of all strokes,
but it has a significant morbidity and mortality associated with it,
particularly in young and middle aged patients.
0:32
Traumatic brain injury is a common cause of subarachnoid hemorrhage,
but does not usually cause a stroke.
I want to focus on spontaneous subarachnoid hemorrhage,
the most common cause of which is a ruptured intracranial aneurysm.
As you can see on this slide,
there are many other causes much less frequent of spontaneous subarachnoid hemorrhage.
0:53
Intracranial aneurysms occur in patients between approximately 35 to 65 years old.
Prevalence of about two to five percent in
the population and there's a significant morbidity and
mortality of about 60 percent overall associated with ruptured intracranial aneurysm.
You can see that the median mortality varies according to country.

The incidence of aneurysmal subarachnoid hemorrhage varies from two to
100,000 in China to ten times that in Finland.
In the US, it's about 12 to 15 for a 100,000 patients.
It's more common in women and interestingly,
significant percentage of patients with aneurysmal subarachnoid hemorrhage have
another family member who also have a confirm intracranial aneurysm.
