The incidence of Ophthalmic Segment Aneurysms is 0.5%~8% 0. Once ruptured, it il Austin subarachnoid hemorrhage(SAH). In addition, while the aneurysms get larger, it will compress the optic nerve, resulting in impaired vision. Because of their close and complex anatomical relationship with neurovascular, dural, and bony structures, the treatment of OSAs is more difficult and riskier than other aneurysms.
ln recent years, with the development of interventional embolic materials and the more stilled techniques of physicians, interventional treatment may be safer for most
patients than minimally invasive surgical treatment for unruptured aneurysms. Compared with surgical clipping, cling rarely causes visual impairment. One study shows that the aneurysmal tamponade rate was more than 95% after treatment with stent-assisted colling for paraclinoid aneurysms 7. However, in fact, individualized
treatment should be used in interventional treatment of this segment of wide-neck aneurysms @. The requirements for devices are also stringent.
Aneurysms with the diameter of less than 5mm are categorized as small aneurysms. Small aneurysms feature small size and thin wall, and most are wide-neck aneurysms, which are flat or oval. Compared with larger aneurysms, their condition will get worse after rupture and bleeding, with a higher disability rate. lnterventional treatment of small aneurysms is difficult. Some papers have reported that the failure rate was 13.7% and the intraoperative rupture rate was 3.9%.
In this article, we will introduce a successful interventional treatment of small ophthalmic segment aneurysms with Perdenser@ EmtbolicCcil System, Perfiller Hydrogel Embolic Coil System and Frepass Disposable Microcatheter.
Male,67 Y. The patient was admitted to the hospital because of aneurysm at the right internal carotid.
