BACKGROUND Stent-assisted coiling is well-established for treatment of cerebral aneurysms. The technique enables treatment of wide-neck, bifurcation and recurrent aneurysms with high packing rates. While described in extenso for laser cut stents, the results of patients treated with the Leo+ Baby (Balt, Montmorency, France) braided microstent are presented. MATERIAL AND METHODS Patients were included if treated with a Leo+ Baby and with digital subtraction angiography (DSA) follow-up available of at least 6 months. Data were evaluated for successful deployment, aneurysm occlusion according to the modified Raymond-Roy classification (MRRC), stent patency and procedure-related morbidity and mortality. RESULTS A total of 81 patients were included and Leo+ Baby deployment was successful in all cases. Coils were used in 80 cases. In 1 case 2 stents were used stent-in-stent without additional coiling. Initial aneurysm occlusion rates were MRRCi1 51.9%, MRRCi2 11.1%, MRRCi3a 24.7% and MRRCi3b 12.3%. Occlusion rates after 6 months were MRRC6m1 78.9%, MRRC6m2 3.9%, MRRC6m3a 6.6% and MRRC6m3b 10.5%. Procedure-related morbidity was 1 case of acute stent thrombosis successfully treated with tirofiban and 1 case with transient hemiparesis due to stent thrombosis after 4 months. There was 1 case of coil-associated subarachnoid hemorrhage (SAH) which caused prolonged hospitalization. No procedure-related mortality was observed. CONCLUSION The results confirm that stent-assisted coiling with the Leo+ Baby stent is safe and efficient for treatment of wide neck or recurrent cerebral aneurysms. Spontaneous progressive aneurysm occlusion over 6 months supports the theory of considerable flow-modulating effects of Leo+ Baby.

使用 Leo+ 婴儿支架的支架辅助卷绕：即刻和中期结果。

背景支架辅助卷绕已被很好地确立用于治疗脑动脉瘤。该技术能够以高填充率治疗宽颈、分叉和复发性动脉瘤。虽然在扩展中描述了激光切割支架，但提供了使用 Leo+ Baby（Balt，Montmorency，法国）编织微型支架治疗的患者的结果。材料和方法 如果接受 Leo+ Baby 治疗并进行至少 6 个月的数字减影血管造影 (DSA) 随访，则纳入患者。根据改良的 Raymond-Roy 分类 (MRRC)、支架通畅性和手术相关的发病率和死亡率，评估了成功部署、动脉瘤闭塞的数据。结果 总共包括 81 名患者，并且 Leo+ Baby 部署在所有情况下均成功。在 80 个案例中使用了线圈。在 1 个案例中，2 个支架使用了支架内支架，没有额外的盘绕。初始动脉瘤闭塞率为 MRRCi1 51.9%、MRRCi2 11.1%、MRRCi3a 24.7% 和 MRRCi3b 12.3%。6 个月后的闭塞率为 MRRC6m1 78.9%、MRRC6m2 3.9%、MRRC6m3a 6.6% 和 MRRC6m3b 10.5%。手术相关的发病率为 1 例急性支架内血栓形成成功，替罗非班治疗成功，1 例因支架内血栓形成 4 个月后出现一过性偏瘫。有 1 例线圈相关蛛网膜下腔出血 (SAH) 导致住院时间延长。没有观察到与手术相关的死亡率。结论 结果证实，使用 Leo+ Baby 支架进行支架辅助盘绕治疗宽颈动脉瘤或复发性脑动脉瘤是安全有效的。
