RESUMO
Intracranial aneurysm ( IA) is one of the most common cerebrovascular diseases in our lves, characterized by high morbidity, high disability rate and high fatality rate. With the extensive application and improvement of imaging techniques, more and more unruptured intracranial aneurysms can be diagnosed and treated before rupture,which reduces the incidence of subarachnoid hemorrhage caused by its rupture. However, the optimal treatment for unruptured aneurysms remains controversial,and the risk of preventive intervention must be weighed against the unknown risk of individual aneurysm rupture. Therefore,it is necessary to predict the risk of rupture before treatment for unruptured aneurysms. In this paper, the high risk factors of IA rupture were discussed through literature research and a large number of clinical data analysis,which provided the basis for the treatment of intracranial aneurysms.
