The bleeding causes swelling of the brain and increased pressure in the skull. The swelling and pressure damage brain cells and tissues. Examples of conditions that can cause a hemorrhagic stroke include high blood pressure, aneurysms, and arteriovenous (ar-TEER-e-o-VE-nus) malformations (AVMs). Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood.
Aneurysms can also occur within the heart itself. As an aneurysm increases in size, the risk of rupture increases. A ruptured aneurysm can lead to bleeding and subsequent hypovolemic shock, leading to death.Aneurysms are a result of a weakened blood vessel wall, and can be a result of a hereditary condition or an acquired disease.Aneurysms can also be a nidus for clot formation (thrombosis) and embolization. ruptured aneurysm can lead to bleeding and subsequent hypovolemic shock, leading to death.
