Causes of cerebral aneurysm formation

Cerebral artery aneurysm may be caused by congenital factors, arteriosclerosis, infection and other reasons.

1. Congenital factors

cerebral artery wall thickness is thin, lack of tissue support around, lack of elastic fibers in the middle of the wall, but the large blood flow, cracks in the middle of the wall, congenital artery dysplasia are important factors in the formation of cerebral artery aneurysm.

2.

Arteriosclerosis occurs in the arterial wall, which cannot withstand great pressure, and at the same time causes arterial nutrient vessel occlusion, causing vessel wall degeneration, which may cause cerebral artery aneurysm.

3.

Infection of various parts of the body stays in the form of small emboli in the weekend branches of cerebral arteries or arterial bifurcations, which may also cause cerebral artery aneurysm.
