Stopping the Bleeding in a Hemorrhagic Stroke

Illustration of a Hemorrhagic StrokeWhen a weakened blood vessel ruptures and spills blood into brain tissue, it’s called a hemorrhagic stroke.  The treatment goal is to stop the bleeding, but understanding the cause is important.

The most common cause for the rupture is uncontrolled hypertension (high blood pressure). There are two other types of weakened blood vessels that can also cause hemorrhagic stroke: aneurysms (swelling within vessels) and arteriovenous malformations or AVMs (abnormal tangles of blood vessels).;
Mechanical Treatment

A small tube called a catheter can sometimes be threaded up through a major artery in an arm or leg and guided into the brain tissue, allowing the surgeon to use cameras to see the problem.

Once the catheter is guided to the source of the bleeding, it deposits a mechanical agent, such as a coil, to prevent further rupture.

This type of procedure is endovascular, meaning that the surgeon gains access through the vascular system, making it less invasive than conventional surgical treatment.

Sometimes surgery is required to secure a blood vessel at the base of the aneurysm.
