Application of high-resolution cone-beam computed tomography for evaluation of endothelialization after flow diverter implantation for unruptured intracranial aneurysms.

Background And Purpose: Although high-resolution cone-beam computed tomography (HR-CBCT) is used for immediate evaluation of stent apposition, studies using this technique to evaluate flow diverter (FD) endothelialization during follow-up are limited. The study aims to investigate the potential of HR-CBCT in assessing FD endothelialization and identify factors influencing poor endothelialization.
Materials And Methods: The clinical and imaging data of patients with unruptured intracranial aneurysms (UIAs) treated by FDs from March 2019 to October 2023 were retrospectively analyzed.

Introduction: Flow-diverting (FD) stents are increasingly used to treat small, unruptured intracranial aneurysms (UIA), but high-quality, unbiased data on initial complications and clinical outcomes were limited in previous literature reviews. We updated the literature review to assess quality, potential bias, complications and short-term outcomes in studies on FD-stents for UIAs.
Patients And Methods: We systematically searched PubMed, Embase and Cochrane Library until January 9, 2025 for studies on FD-stents for UIAs.

Chronological Changes in Intra-aneurysmal Signal Intensity on T1-weighted Black Blood Images after Endovascular Treatment for Unruptured Intracranial Aneurysms.

Intra-aneurysmal thrombus formation is crucial for the healing of endovascularly treated aneurysms. This study evaluated whether T1-weighted black blood imaging can monitor thrombus formation by examining the relationship between chronological signal intensity changes and aneurysm occlusion status after flow diverter stenting and coil embolization. We retrospectively analyzed 78 patients with 83 aneurysms (flow diverter stenting: 28, coil embolization: 55) who underwent T1-weighted black blood imaging at 1 week, 3 months, and 6 months post-treatment.

Background: Blister-like intracranial aneurysms are rare fragile lesions with a high risk of rupture leading to acute subarachnoid hemorrhage (aSAH) and significant morbidity. Flow diversion (FD) has emerged as a promising endovascular treatment, particularly for complex cases unsuitable for clipping or coiling, but evidence in ruptured settings remains limited due to challenges such as the risks of dual antiplatelet therapy. This study aimed to evaluate the efficacy and safety of FD in ruptured blister-like aneurysms during aSAH through a systematic review and meta-analysis.
