Subarachnoid hemorrhage (SAH) is a subtype of stroke that is most commonly caused by the rupture of intracranial aneurysm. Endovascular occlusion of intracranial aneurysms has emerged as an alternative to the established microsurgical clipping, The decision process when choosing a treatment for ruptured intracranial aneurysm should comprise an algorithm that was based on the characteristics of the aneurysm and patient status, age, and neurological condition, rather than a blanket assumption that one modality is superior to another. 展开更多
