Brain aneurysm bulges out of a weakened spot in an artery wall. The weakening results from an abnormal loss of the tissue making up the muscular layer of the artery. If that weak area ruptures, blood flows into the brain cutting off oxygen to brain cells, a situation that can cause permanent disability or even be fatal.
it can be similar to heart attacks. Just like a person may have no warning of an impending heart attack, there almost is never a warning that a brain aneurysm is about to rupture. Fortunately, through imaging screening techniques, individuals at high risk of harboring a brain aneurysm can be identified easily with non-invasive imaging tests.
Two quick and safe ways to screen for aneurysms include MRI with MRA (Magnetic Resonance Imaging with angiography) and CT with CTA (Computed Tomography with Angiography). Images that are obtained during these studies will reliably detect aneurysms as small as 2 mm. There are advantages and disadvantages of each of these types of studi...
About 90% of all brain aneurysms produce no symptoms
Brain aneurysms are most prevalent in people ages 35 – 60, but can occur in children as well. The median age when aneurysmal hemorrhagic strokeoccurs is 50 years old and there are typically no warning signs.
4 out of 7 people who recover from a ruptured brain aneurysm will have disabilities.
Most aneurysms are small, about 1/8 inch to nearly one inch, and an estimated 50 to 80 percent of all aneurysms do not rupture during the course of a person’s lifetime. Aneurysms larger than one inch are referred to as “giant” aneurysms and can pose a particularly high risk and can be difficult to treat.
1 in 4 survivors of a rupture experience some permanent disability
Ruptured brain aneurysms account for 3 – 5% of all new strokes.
The annual rate of rupture is approximately 8 – 10 per 100,000 people or about 30,000 people in the United States suffer a brain aneurysm ruptur...
Aneurysm is a ballooning at a weak spot in an artery wall. It may leak or rupture, causing bleeding into the brain (hemorrhagic stroke). Most often a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain. Neurologist use multiple tests to confirm a brain aneurysm diagnosis:
MRA: A magnetic resonance angiogram (MRA) scan is a type of MRI scan that’s specifically for blood vessels.
CTA: This is a special type of CT scan that focuses on the blood vessels.
Angiogram: For a traditional angiogram, doctors insert a catheter (a thin tube) into your body to see your blood vessels more clearly. It’s the gold standard for diagnosing brain aneurysms because it gives a 3-D view of an aneurysm, offering precise details that help determine the best treatment for you.
