What causes hemorrhagic stroke?
• Malformed Blood Vessels Blood flows from the heart to the body through blood vessels called arteries. Arteries are thick and strong, like a fire hose. Arteries have to be strong because blood flows from the heart to the body quickly with a lot of pressure. In the body, big arteries branch off into smaller and smaller blood vessels that help to slow the blood down before it enters the veins and travels back to the heart. Veins are thin and floppy, like a water balloon. Veins do not have to be strong like arteries because blood flows through veins to the heart very slowly. In a normal body, the fast-moving, high-pressure blood in the arteries always slows down before it gets to the veins. Some children are born with big arteries that connect directly to veins without any small branches to slow the blood down. This is like filling a water balloon with a fire hose — the thin, floppy vein cannot handle the fast-moving, high-pressure blood coming from the thick, strong artery. Under this
