BACKGROUND/OBJECTIVE Compliant dual-lumen balloon microcatheters have been used to perform balloon-assisted embolization (BAE) of brain arteriovenous malformations (AVMs) with ethylene vinyl alcohol copolymer (Onyx). However, vessel rupture and microcatheter retention have been reported from BAE using these microcatheters. Using an extra-compliant balloon microcatheter (Scepter XC; Microvention, Tustin, CA, USA) could help avoid pial vessel rupture during BAE. We herein report our experience using this balloon microcatheter for BAE. METHODS This retrospective study included patients who underwent BAE of brain AVMs at our institution between June 2012 and March 2017. RESULTS The extra-compliant Scepter XC balloon microcatheter was used for BAE of brain AVMs in 23 patients aged 44.3 ± 16.7 years (range 0-65 years). A total of 40 intracranial vessels (39 pial arteries and 1 pial vein) were catheterized and embolized during 30 separate sessions. In all instances, the balloon microcatheter could be successfully advanced to the AVM nidus. A mean volume of 2.4 ± 1.7 mL (range 0.65-4.6 mL) of Onyx was injected per session. There were no instances of vessel rupture, microcatheter retention, or stroke. CONCLUSION Utilization of the extra-compliant balloon microcatheter results in safe and effective BAE, which adds to the growing experience with BAE for AVM treatment.

重新审视脑动静脉畸形缟玛瑙球囊辅助栓塞的安全性和可行性：Sceptre XC 球囊微导管的个人经验。

背景/目的顺应性双腔球囊微导管已被用于使用乙烯乙烯醇共聚物 (Onyx) 对脑动静脉畸形 (AVM) 进行球囊辅助栓塞 (BAE)。然而，使用这些微导管的 BAE 报告了血管破裂和微导管滞留。使用超柔顺的球囊微导管（Scepter XC；Microvention，Tustin，CA，USA）有助于避免 BAE 期间软脑膜血管破裂。我们在此报告我们使用这种球囊微导管进行 BAE 的经验。方法 这项回顾性研究纳入了 2012 年 6 月至 2017 年 3 月在我们机构接受 BAE 脑 AVM 的患者。结果 23 名年龄为 44.3 ± 16.7 岁（范围 0- 65 岁）。在 30 次单独的疗程中，总共 40 条颅内血管（39 条软脑膜动脉和 1 条软脑膜静脉）被置管和栓塞。在所有情况下，球囊微导管都可以成功推进到 AVM 病灶。每次注射平均体积为 2.4 ± 1.7 mL（范围 0.65-4.6 mL）的 Onyx。没有发生血管破裂、微导管滞留或中风的情况。结论 使用超顺应性球囊微导管可实现安全有效的 BAE，这增加了 BAE 治疗 AVM 的经验。没有发生血管破裂、微导管滞留或中风的情况。结论 使用超顺应性球囊微导管可实现安全有效的 BAE，这增加了 BAE 治疗 AVM 的经验。没有发生血管破裂、微导管滞留或中风的情况。结论 使用超顺应性球囊微导管可实现安全有效的 BAE，这增加了 BAE 治疗 AVM 的经验。
