【摘要】 目的 探讨血流导向装置（FD）治疗大脑前动脉动脉瘤的安全性和疗效。方法 回顾性分析2019年2月至2022年8月郑州大学第一附属医院神经介入科收治的FD治疗大脑前动脉动脉瘤24例。术后采用O’Kelly Marotta(OKM)分级标准判断动脉瘤的闭塞程度，采用改良Rankin量表评分（mRS）评估临床预后（0～2分为预后良好，3～5分为预后不良）。结果 24例患者（24枚动脉瘤）共置入24枚支架，支架置入成功率为100%。围手术期发生2例（8.3%）并发症，1例为出血性事件，1例为缺血性事件。术后随访24例患者中mRS评分均≤2分。随访中24例患者经影像学检查，OKM分级B级2例（8.3%）,C级6例（25%），其余16例（66.7%）患者完全愈合（D级）。结论FD是一种安全和有效的治疗大脑前动脉动脉瘤的方式。术后和长期随访结果中没有严重的缺血性或出血性并发症，也没有观察到神经病学并发症。更多还原

【Abstract】 Objective To investigate the safety and efficacy of flow-directed devices(flow diverter, FD) in the treatment of intracranial anterior cerebral artery aneurysms(ACAA). Methods The clinical data of 21 patients with ACAA, who were admitted to the Department of Neurointerventional Medicine of the First Affiliated Hospital of Zhengzhou University of China to receive FD treatment between February 2019 and August 2022, were retrospectively analyzed. After the treatment, O’Kelly Marotta(OKM) grading criteria was used to determine the degree of occlusion of the aneurysm, and the modified Rankin Scale(mRS) score was adopted to assess the clinical prognosis(0-2 points being defined as a good prognosis, and 3-5 points being defined as a poor prognosis).Results A total of 24 FD stents were implanted in 24 patients(24 aneurysms in total), and the technical success rate of stent implantation was 100%. During the perioperative period, complications occurred in 2 patients(8.3%), including hemorrhagic event(n=1) and ischemic event(n=1). The mRS score in all the 24 patients was ≤2 points. Follow-up imaging examination showed that OKM grade B was seen in 2 patients(8.3%), grade C in 6 patients(25%), and grade D(complete healing) in 16 patients(66.7%).Conclusion For the treatment of ACAA, the FD stent implantation is a safe and effective method. During the postoperative and the long-term follow-up period, neither serious ischemic or hemorrhagic complications nor neurological complications are observed.(J Intervent Radiol, 2024, 33: 711-716)更多还原
