Pediatric Hemorrhagic Stroke
A hemorrhagic stroke is when a blood vessel ruptures (bursts) and blood accumulates in the tissue surrounding the rupture.
A stroke occurs when blood flow to the brain is reduced or cut off completely for a period of time. When oxygen-rich blood can’t reach brain cells, they can die quickly. This can cause permanent brain damage.
One type of stroke is a hemorrhagic stroke. According to the American Heart Association/American Stroke Association, this accounts for about 13 percent of all strokes.
In a hemorrhagic stroke, a weakened blood vessel ruptures and bleeds into surrounding brain. The resulting blood pools and compresses the tissue.
Two types of hemorrhagic strokes can occur:
- Intracerebral hemorrhage – This is a stroke that causes bleeding in the brain.
- Subarachnoid hemorrhage – This type of stroke causes bleeding within the subarachnoid space, the area between the brain and the tissues covering the brain.
Two forms of weakened blood vessels typically cause a hemorrhagic stroke:
- Aneurysm – Bulge or ballooning in a blood vessel in the brain
- Arteriovenous malformation (AVMs) – group of abnormally formed blood vessels
Symptoms of a hemorrhagic stroke may include:
- Confusion or disorientation
- Loss of balance
- Nausea or vomiting
- Problems with speech or swallowing
- Sudden, severe headache
- Total or partial loss of consciousness
- Weakness or tingling in the face, leg or arm on one side of the body
