Herein, we describe a technique for stent-assisted coil embolization with a spring-shaped microcatheter in a patient with an M1 ultrawide-necked circumferential aneurysm in the middle cerebral artery (MCA). A 49-year-old man was referred for treatment of an incidentally detected M1 large-circumference aneurysm on magnetic resonance angiography. Subsequent digital subtraction angiography revealed an 18.2×16.5 mm ultrawide-necked circumferential aneurysm on the distal M1 portion of the left MCA, and we planned stent-assisted coil embolization using a spring-shaped microcatheter. After we deployed the stent, we performed coil embolization under the down-the-barrel view by pulling out the microcatheter little by little. Using this technique, we could fill the coil mass evenly into the aneurysmal sac around the stent. And there were no immediate or delayed complications after the procedure. Stent-assisted coiling using a spring-shaped microcatheter is a useful and safe technique for treating ultrawide-necked circumferential aneurysm or fusiform aneurysms.
在此，我们介绍了一种在大脑中动脉（MCA）M1 极宽颈周缘动脉瘤患者中使用弹簧状微导管进行支架辅助线圈栓塞的技术。一名 49 岁男性因磁共振血管造影偶然发现 M1 大周长动脉瘤而被转介治疗。随后的数字减影血管造影显示左侧 MCA 远端 M1 部分有一个 18.2×16.5mm 的极宽颈周缘动脉瘤，我们计划使用弹簧状微导管进行支架辅助线圈栓塞。在放置支架后，我们通过一点一点地拔出微导管，在桶下视图下进行线圈栓塞。使用这种技术，我们可以将线圈均匀地填充到支架周围的动脉瘤囊中。并且在手术后没有立即或延迟并发症。使用弹簧状微导管的支架辅助线圈栓塞是治疗极宽颈周缘动脉瘤或梭形动脉瘤的一种有用且安全的技术。
