Data from Pipeline Vs Surpass Flow Diversion Study

Patients who underwent a flow diversion procedure with Pipeline Embolization Device, Pipeline Flex, and Surpass Streamline from October 2012 to February 2020 were included in the study. Demographic data including age, sex, comorbidities, and history of previous aneurysm treatment were collected by the authors at each center from the electronic medical record. Aneurysm laterality, location, morphology, dome height, and neck width were recorded from digital subtraction angiography. For aneurysms located in the cavernous portion of the internal carotid artery (cICA), digital subtraction angiography images were extracted to assess cICA tortuosity using a I-IV grading scale.14 Two authors (C.F. and J.V.-S.) independently reviewed and classified the tortuosity of each cICA case, with each blinded to the other’s assessments. Any discordant grading between these authors was resolved by a third author (R.H.), who acted as a tiebreaker and determined the final tortuosity grade. Procedural details including case duration, radiation exposure, and the number of flow diverters deployed were extracted from the operative notes. Technical metrics of the procedures included the success of device deployment, foreshortening, kinking, or adjuvant device use. Periprocedural adverse incidents occurring up to when the patient was discharged from the FD procedure were recorded as well.

本研究纳入2012年10月至2020年2月期间接受Pipeline栓塞装置（Pipeline Embolization Device）、Pipeline Flex及Surpass Streamline行血流导向术的患者。研究人员从各中心的电子病历中收集患者的年龄、性别、合并症及既往动脉瘤治疗史等人口学资料。从数字减影血管造影（digital subtraction angiography）中记录动脉瘤的侧别、位置、形态、瘤顶高度与瘤颈宽度。针对位于颈内动脉海绵窦段（cavernous portion of the internal carotid artery, cICA）的动脉瘤，提取其数字减影血管造影图像，采用I~IV级分级量表评估颈内动脉海绵窦段的迂曲程度（参考文献14）。两位作者（C.F.与J.V.-S.）独立对每例颈内动脉海绵窦段病例的迂曲程度进行回顾与分级，且双方均对彼此的评估结果设盲。若两位作者的分级结果存在分歧，则由第三位作者（R.H.）作为仲裁者确定最终的迂曲分级。从手术记录中提取手术时长、辐射暴露量及植入的血流导向装置数量等手术相关细节。手术技术指标包括装置植入成功率、支架缩短、支架扭结或辅助装置使用情况。同时记录自血流导向术至患者出院期间发生的所有围手术期不良事件。
