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.
1:17
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.
