Endovascular management of internal carotid artery terminus aneurysms: a systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Internal carotid artery (ICA) terminus aneurysms are a rare subtype of intracranial aneurysms with distinct hemodynamic characteristics and treatment challenges. This study aims to evaluate clinical outcomes associated with different endovascular approaches for ICA terminus aneurysms through a systematic review and meta-analysis. A comprehensive literature search through PubMed and Scopus from inception to July 2025. Data on patient demographics, aneurysm characteristics, and outcomes of coil embolization, stent-assisted coiling, and FD were extracted. Pooled analyses and subgroup comparisons were performed following PRISMA guidelines. Among 322 patients, primary coil embedding (59.0%) was the most used modality, followed by stent-assisted coiling (30.1%) and flow diversion (FD) (10.2%). A good functional outcome (mRS 0–2) was achieved in 74.5%, and complete occlusion in 72.4%. Primary coil embedding demonstrated significantly lower stroke (OR = 0.193, 95% CI: 0.056–0.662) and mortality (OR = 0.234, 95% CI: 0.045–0.906) compared to FD. Stent-assisted coiling achieved the highest rate of favorable outcomes (97.7%) and lowest recurrence (8.1%). Ruptured aneurysms were associated with worse outcomes, including lower occlusion (41–59%) and higher mortality (9.4%) than unruptured cases (occlusion: 94.5%, mortality: 2.0%). Endovascular strategies are commonly used in the management of ICA terminus aneurysms and demonstrate overall acceptable clinical and radiographic outcomes in contemporary practice. Observed differences among treatment modalities likely reflect underlying aneurysm morphology, clinical context, and treatment selection rather than intrinsic differences in device performance. Therefore, modality choice should be individualized based on anatomical and clinical considerations, and current findings should be interpreted as descriptive and hypothesis-generating.
