A cerebral aneurysm occurs when a blood vessel weakens or “balloons.” If the vessel ruptures and bleeds into the brain, a hemorrhagic stroke happens, according to the American Stroke AssociationOff Site Icon.

Aneurysm clipping or coil embolization may be used to treat a hemorrhagic stroke caused by a ruptured aneurysm, according to the National Stroke AssociationOff Site Icon.

Aneurysm clipping is when the surgeon places a tiny clamp at the base of the aneurysm to stop the bleeding, according to the NSA. With a coil embolization, a catheter is guided through the blood vessels to the aneurysm at which point a coil is released. The coil causes a blood clot to form, which blocks blood flow and prevents the aneurysm from bursting again, according to the NSA.
