IntroductionSuperbore 0.088″ catheters provide a platform for optimizing aspiration efficiency and flow control during stroke mechanical thrombectomy procedures. New superbore catheters have the distal flexibility necessary to navigate complex neurovascular anatomy while providing the proximal support of traditional 8F catheters. The safety and feasibility of Zoom 88™ superbore angled-tip catheters in the middle cerebral artery (MCA) segments smaller than the catheter diameter have not been previously described.MethodsTwenty consecutive cases of acute MCA mechanical thrombectomy were retrospectively identified from the senior authors’ prospectively maintained Institutional Review Board-approved database, in which the Zoom 88 (Imperative Care, Campbell, CA) catheter was successfully navigated to at least the M1 segment. Patient demographics, procedural details, and periprocedural information were analyzed. Rates and averages (standard errors) are generally reported.ResultsThe average National Institutes of Health Stroke Scale at presentation and age were 15 ± 2 and 73 ± 3 years, respectively. The M1 and M2 occlusions were evenly distributed. The average M1 measurements before thrombectomy ranged from 2.36 ± 0.07 mm proximally to 2.00 ± 0.11 mm distally, and after thrombectomy, they ranged from 2.34 ± 0.07 mm proximally to 1.97 ± 0.10 mm distally. First-pass modified thrombolysis in cerebral infarction (mTICI) 2C/3 recanalization was achieved in 40% of cases, and final mTICI 2C/3 recanalization was achieved in 90% of cases. A single case of mild vasospasm was managed with verapamil. No hemorrhagic or periprocedural complications were noted.ConclusionSuperbore 0.088″ catheters with flexible distal segments can be safely navigated to the MCA to augment mechanical thrombectomy even when the MCA segment is smaller than the catheter.

小于8 French的M1血管超口径0.088英寸机械取栓的可行性：连续20例经验

简介Superbore 0.088" 导管提供了一个平台，可在中风机械血栓切除术过程中优化抽吸效率和流量控制。新型 Superbore 导管具有在复杂的神经血管解剖结构中导航所需的远端灵活性，同时提供传统 8F 导管的近端支撑。Zoom 88™超孔径斜尖导管在小于导管直径的大脑中动脉（MCA）段的安全性和可行性之前尚未被描述。方法从资深作者的前瞻性研究中回顾性鉴定连续20例急性MCA机械血栓切除术维护机构审查委员会批准的数据库，其中 Zoom 88（紧急护理，坎贝尔，加利福尼亚州）导管至少成功导航至 M1 段。分析了患者人口统计、手术细节和围手术期信息。一般会报告比率和平均值（标准误差）。结果 美国国立卫生研究院卒中量表就诊时的平均年龄和年龄分别为 15 ± 2 岁和 73 ± 3 岁。M1和M2遮挡分布均匀。血栓切除术前的平均 M1 测量值范围为近端 2.36 ± 0.07 mm 至远端 2.00 ± 0.11 mm，血栓切除术后，平均 M1 测量值范围为近端 2.34 ± 0.07 mm 至远端 1.97 ± 0.10 mm。脑梗死改良溶栓（mTICI）首过2C/3再通率40%，最终mTICI 2C/3再通率90%。一例轻度血管痉挛患者使用维拉帕米进行治疗。没有发现出血或围手术期并发症。 结论 即使 MCA 段比导管小，具有柔性远端段的 Superbore 0.088" 导管也可以安全地导航至 MCA 以增强机械血栓切除术。
