Some aneurysms will not rupture in lifetime, no obvious clinical symptoms or only mild clinical symptoms, which need not be special treatment; some aneurysms can rupture in young ages, even life-threatening. Therefore, it is of great clinical significance to assess the risk factors and the inducing factors of intracranial aneurysms rupture.
