A 29-year-old patient attended our institution for recurrent strokes related to a giant partially thrombosed M1 aneurysm. Superficial temporal artery-middle cerebral artery (STA-MCA) bypass and subsequent occlusion of both the aneurysm and the dysplastic M1 segment were planned. However, owing to the shortness of the non-dysplastic segment of M1 and the risk of occlusion of the lenticulostriate arteries, the use of a double-lumen balloon was considered for coiling and subsequent injection of Onyx. STA-MCA bypass was performed using a regular technique. Endovascular occlusion of both the aneurysm and the parent artery was subsequently performed by means of coils and Onyx-34 that was injected via the Ascent balloon under balloon inflation. No complications were recorded and no stroke was observed on control MRI. The injection of Onyx-34 through a double-lumen balloon under balloon inflation is a quick and safe technique for precise occlusion of a parent artery.
一名29岁的患者因巨大的部分血栓形成的M1动脉瘤相关的复发性中风前来我院就诊。计划进行颞浅动脉-大脑中动脉（STA-MCA）搭桥术，随后对动脉瘤和发育异常的M1段进行闭塞。然而，由于M1非发育异常段较短以及豆纹动脉闭塞的风险，考虑使用双腔球囊进行栓塞并随后注入Onyx。采用常规技术进行STA-MCA搭桥术。随后通过弹簧圈和在球囊充盈下经Ascent球囊注入的Onyx-34对动脉瘤和供血动脉进行血管内闭塞。未记录到并发症，在对照MRI上未观察到中风。在球囊充盈下通过双腔球囊注入Onyx-34是一种快速且安全的技术，可精确闭塞供血动脉。
