With the improvement of new intervention materials and technologies, intravascular treatment is safer and more effective for the ophthalmic segment aneurysms and can avoid damage to the optic nerve, and thus it hardly ever causes visual impairment when being compared with surgical clipping. One study reported that the occlusion rate of paraclinoidal aneurysms treated with stent-assisted coils was more than 95%, and that of paraclinoidal aneurysms only treated with coion was only 54.2%. However, in fact, individualized treatment should be also used for wide-necked aneurysms in addition to intravascular treatment. Therefore, higher requirements are imposed to instruments.
Basic information about the patient:
