•        Post-injury: Trauma can harm the aortic divider and cause prompt harm or it might cause a territory of shortcoming that will frame an aneurysm after some time.

•        Arteritis: Inflammation of veins as happens in Takayasu sickness, monster cell arteritis, and backsliding polychondritis can add to aneurysm.
