How big an aneurysm grows in a year is correlated with many factors and cannot be generalized, and there is no uniform standard or projection formula.
Aneurysm is an abnormal bulge on the wall of arterial vessels. Current research considers that the formation of aneurysm may be related to congenital defects in the muscular layer of the arterial wall or acquired lesions of the elastic layer of the blood vessel. With age, atherosclerosis increases, the elasticity of the vessel wall decreases, and under the constant impact of blood flow, the weak vessel wall may bulge outward to form an aneurysm.
The growth and rupture of aneurysm is correlated with various factors, such as family history of aneurysm, obesity, high blood pressure fluctuation, smoking, hyperlipidemia, excessive alcohol consumption, heavy physical labor, and application of special drugs.
When an aneurysm is detected, there is no need to be overly nervous. Strict control of risk factors, regular review, and surgical intervention can be considered if necessary.
