MICROANATOMY

Detailed explanation-1: -Brain aneurysms are caused by thinning artery walls. Aneurysms often form at forks or branches in arteries because those areas of the vessels are weaker. Although aneurysms can appear anywhere in the brain, they’re most common in arteries at the base of the brain.

Detailed explanation-2: -What is an aneurysm? An aneurysm is a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning greater than 50% of the vessel’s normal diameter (width). An aneurysm may occur in any blood vessel, but is most often seen in an artery rather than a vein.

Detailed explanation-3: -In some cases, the plaque is part of a process that causes a weakening of the wall of an artery. This can lead to a bulge in an artery called an aneurysm. Aneurysms can break open (rupture). This causes bleeding that can be life threatening.

Detailed explanation-4: -An aneurysm is an abnormal swelling or bulge in the wall of a blood vessel, such as an artery. Aneurysms can occur anywhere throughout the circulatory system, but most commonly develop along the aorta (the body’s main artery that runs the length of the trunk) and in blood vessels of the brain.
