Aneurysm Causes

Aneurysm is a permanent swelling disease that caused by weak artery wall. Aneurysm formation at any site, but the most common occurrence of aneurysm is in the cerebral artery, aorta, and the heart to pump blood to the main artery of the body. Artery aneurysm causes is congenital defects for arterial wall, atherosclerosis or high blood pressure, arteritis, mycotic aneurysm, infective endocarditis.

1, the arterial wall have three organizations, the forces that support the artery is provided by the middle of the muscle layer, and this layer may have congenital defects. The affected artery in the normal blood pressure may result in a balloon-like swelling, this swelling called a capsule-shaped aneurysm. As a result of congenital defects caused by aneurysm is almost always occurred in the cerebral arteries at the base, because of its shape as well as a number of regular convergence of Health aneurysm together, they are also called "berry" aneurysm.

2, trauma, arteritis, and mycotic aneurysm is the less causes of aneurysm. Mycotic aortic aneurysm occur in the arterial wall or local bacterial or fungal infection site, which is usually caused by septicemia with metastatic infection, the most common aneurysm causes is infective endocarditis. infection can also spread to the local vessel wall, pre-existing aortic aneurysm or artery can be infected, usually by hematogenous disseminated.

3, the middle part of arterial wall muscle as a result of atherosclerosis or high blood pressure and slow the deterioration of chronic diseases. From atherosclerosis caused by aneurysm is likely to be a sausage-shaped enlargement, the aneurysm fusiform aneurysm is called, it will be a small section along the artery developed. Another similarity is the swelling caused by high blood pressure. However, arterial blood pressure in the increased arterial wall will to expand in many different ways. It may even burst artery wall organization layer, forcing the blood into the organization into layers. The disease is called vein tumor dissection.
