摘要：

Abstract:

 The mortality and morbidity rate of subarachnoid hemorrhage is quite high. The incidence of intracranial aneurysmal subarachnoid hemorrhage in women, especially in postmenopausal women, is significantly higher than that in men, which is related to estrogen deficiency. Estrogen replacement therapy can reduce the risk of developing it.
