Brain death results from brain damage that may result from factors such as cardiac arrest that affects blood vessels in the heart. Another condition that affects blood vessels is berry aneurysm, which affects the artery walls in the brain. Berry aneurysm is commonly referred to as saccular brain aneurysm. The artery in the brain is composed of two muscle layers and one elastic layer. Berry aneurysm results when the sac like or berry like enlargements form on the two muscle tissues and the elastic tissue on the wall of the arteries in the brain and then rapture (Vajkoczy & Hartmann, 2002). Provide a brief pathophysiology of berry aneurysm and how rupture can lead to brain death These berry-like enlargements commonly form at congenitally weak spots in a ring of arteries at the base of the brain or the circle of Willis (Vajkoczy & Hartmann, 2002). The circle of wills receives blood from all the major arteries in the brain and circulates to other areas of the brain. This leads to intracranial hemorrhage and raptured berry aneurysms are common in people 40 to 60 years old. Intracranial hemorrhage presents where the artery raptures and the leaking blood cause a hematoma which applies pressure on the brain tissue. Further bleeding causes increased hematoma which further compresses the brain tissu...
