研究目的: |
本研究为非劣效、多中心、前瞻性、随机对照临床试验,拟纳入符合标准的颅内后循环未破裂动脉瘤患者,按 1:1 随机分为血流导向装置(FD)治疗组与普通支架(CS)联合弹簧圈栓塞治疗组,通过规范围手术期管理与标准化随访,开展以下研究目的: 主要目的:以术后 12 个月改良 Rankin 量表(mRS)评分≤2 分的良好神经功能预后率为主要终点,验证血流导向装置治疗颅内后循环动脉瘤的安全性不劣于普通支架(非劣效界值设定为 8%),为该类病变的血管内治疗策略选择提供高级别循证医学证据。 次要目的:① 比较两组术后 12 个月动脉瘤完全闭塞率(Raymond?Roy Ⅰ 级),评价血流导向装置的中长期有效性;② 观察并比较术后 30 天主要不良事件(穿支梗死、支架内血栓、动脉瘤破裂、全因死亡)发生率,明确两种术式的短期安全风险;③ 探索影响预后的关键因素,为颅内后循环动脉瘤个体化介入治疗提供临床参考。 总体目标:弥补当前颅内后循环动脉瘤血流导向治疗前瞻性、多中心、对照证据不足的短板,规范诊疗路径,提升临床疗效与患者预后,推动神经介入领域高质量临床研究与技术规范化应用。 |

Objectives of Study: |
Primary ObjectiveTo evaluate the non-inferiority of safety of flow diverter (FD) implantation compared with conventional stent (CS) assisted coiling for unruptured intracranial posterior circulation aneurysms, using the favorable functional outcome rate (modified Rankin Scale, mRS <= 2) at 12 months postoperatively as the primary endpoint, with a non-inferiority margin of 8%.Secondary ObjectivesTo compare the complete aneurysm occlusion rate (Raymond-Roy grade I) between the two groups at 12 months postoperatively.To assess the incidence of major adverse events within 30 days postoperatively, including perforator infarction, in-stent thrombosis, aneurysm rupture, and all-cause death.To explore clinical and imaging factors associated with prognosis in patients with intracranial posterior circulation aneurysms undergoing endovascular treatment. |

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址): |
研究原始数据实行授权访问制。数据统一存储于各参研中心加密数据库,仅在获得研究负责人书面授权后,方可向具备合规研究目的的外部研究者共享;共享前将对数据进行匿名化处理,严格保护受试者隐私与研究知识产权,未经授权严禁复制、传播与使用。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
Raw study data are available only upon authorized request. Data are stored in encrypted databases at participating centers. Access will be granted to external researchers only after written approval from the principal investigator for legitimate research purposes. All shared data will be de-identified to protect participant privacy and intellectual property rights. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究采用纸质 / 电子版病例报告表(CRF) 进行数据采集,由经过统一培训的研究者按研究方案及时、准确、完整录入受试者基线、手术、随访及不良事件等全部信息。数据管理采用Excel 电子表格进行双人双录入、核对与清洗,确保数据一致性与准确性;研究数据统一加密存储,设置访问权限,定期备份,严格保障数据安全、完整与可溯源。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data will be collected using case report forms (CRF). All data including baseline characteristics, procedure details, follow-up outcomes and adverse events will be recorded accurately by trained investigators.Data management will be conducted using Excel with double data entry and verification to ensure accuracy. All data will be stored securely in encrypted files with restricted access and regular backups to ensure integrity and traceability. |
