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.
一位 29 岁的患者因与巨大部分血栓形成的 M1 动脉瘤相关的复发性中风到我院就诊。计划进行颞浅动脉-大脑中动脉（STA-MCA）旁路手术，随后闭塞动脉瘤和发育不良的 M1 段。然而，由于 M1 的非发育不良段较短，且纹状体动脉闭塞的风险较高，因此考虑使用双腔球囊进行弹簧圈栓塞和随后的 Onyx 注射。采用常规技术进行 STA-MCA 旁路手术。随后通过弹簧圈和通过 Ascent 球囊在球囊膨胀下注射的 Onyx-34 进行动脉瘤和母动脉的血管内闭塞。未记录到并发症，且在对照 MRI 上未见中风。在球囊膨胀下通过双腔球囊注射 Onyx-34 是一种快速且安全的技术，可用于精确闭塞母动脉。
