Abstract

Purpose: The Woven EndoBridge (WEB) device is an established endovascular treatment method for wide-neck intracranial aneurysms. Digital subtraction angiography (DSA) is the reference standard for posttreatment evaluation; however, its invasive nature limits its repeated use. This study aimed to compare the diagnostic accuracy and reproducibility of intravenous cone-beam computed tomography (IVCBCT) and DSA in the follow-up of aneurysms treated with the WEB device.

Methods: This prospective single-center study included 16 patients with unruptured intracranial aneurysms who were treated with the WEB device. All patients underwent both DSA and IVCBCT at the 6‑month follow-up, performed on the same day. Aneurysm occlusion status was independently evaluated by two experienced neuroradiologists using the 8‑point modified Bicêtre Occlusion Scale Score (BOSS). Intermodality and interobserver agreement were assessed using Cohen's kappa statistics.

Results: Complete agreement between IVCBCT and DSA was observed in all 16 cases (κ = 1.0 for both raters). Interobserver agreement for IVCBCT grading was also excellent (κ = 0.86). The BOSS distribution for IVCBCT was as follows: grade 0 or 0' in eight cases (50.0%), grade 1 in five cases (31.3%), grade 2 in two cases (12.5%), and grade 3 in one case (6.2%). IVCBCT demonstrated consistent diagnostic performance across various occlusion grades.

Conclusion: IVCBCT offers a reliable, noninvasive alternative to DSA for the follow-up of WEB-treated aneurysms, providing excellent diagnostic concordance and reproducibility.

经静脉锥形束CT观察编织腔桥装置治疗颅内动脉瘤的随访。

目的：Woven EndoBridge （WEB）装置是一种成熟的宽颈颅内动脉瘤的血管内治疗方法。数字减影血管造影（DSA）是术后评价的参考标准；然而，它的侵入性限制了它的重复使用。本研究旨在比较静脉锥束计算机断层扫描（IVCBCT）和DSA在使用该装置治疗的动脉瘤随访中的诊断准确性和再现性。方法：本前瞻性单中心研究纳入16例使用WEB装置治疗的未破裂颅内动脉瘤患者。所有患者在6个月的随访中均在同一天接受了DSA和IVCBCT检查。动脉瘤闭塞状态由两名经验丰富的神经放射科医生独立评估，采用改良的8分Bicêtre闭塞量表评分（BOSS）。使用Cohen's kappa统计评估多式联运性和观察者间的一致性。结果：所有16例患者的IVCBCT和DSA评分完全一致（κ = 1.0）。IVCBCT分级的观察者间一致性也很好（κ = 0.86）。IVCBCT的BOSS分布为：0级或0′级8例（50.0%），1级5例（31.3%），2级2例（12.5%），3级1例（6.2%）。IVCBCT在不同的闭塞等级中表现出一致的诊断性能。结论：IVCBCT为web治疗动脉瘤的随访提供了可靠的、无创的替代DSA的方法，具有良好的诊断一致性和可重复性。
