Peripheral brain aneurysms arise from the distal segments of cerebral arteries. They can be treated by surgery or by an endovascular approach. We present our experience of endovascular treatment of peripheral brain aneurysms with a novel endovascular device, the Guglielmi detachable coil (GDC) "crescent."
The GDC "crescent" is a 5-mm long, curved coil steerable beyond the tip of a microcatheter and detachable at a distance. The GDC "crescent" was used in three cases of intracranial peripheral aneurysms to occlude their parent vessel.
Three peripheral brain aneurysms in three patients were successfully treated with parent vessel occlusion using the prototype GDC "crescent" coils, thereby excluding the aneurysms from the brain circulation. No complications were encountered.
From this limited experience, the GDC "crescent" seems particularly suitable for the controlled endovascular occlusion of the often-narrow parent artery of distal brain aneurysms.
周围性脑动脉瘤起源于脑动脉的远端节段。它们可以通过手术或血管内介入方法进行治疗。我们展示了使用一种新型血管内装置—— Guglielmi 可解脱弹簧圈（GDC）“新月型”对周围性脑动脉瘤进行血管内治疗的经验。
GDC“新月型”是一种长 5 毫米的弯曲弹簧圈，可在微导管尖端之外进行操控并可在一定距离处解脱。GDC“新月型”被用于 3 例颅内周围性动脉瘤，以闭塞其供血动脉。
3 例患者的 3 个周围性脑动脉瘤使用原型 GDC“新月型”弹簧圈成功进行了供血动脉闭塞治疗，从而使动脉瘤从脑循环中排除。未出现并发症。
基于这一有限的经验，GDC“新月型”似乎特别适合对远端脑动脉瘤通常较狭窄的供血动脉进行可控的血管内闭塞。
