Aneurysms Associated with Hyperplastic Anterior Choroidal Arteries: Three Cases with Literature Review.
Article in Journal of neuroendovascular therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objective: A hyperplastic anterior choroidal artery (AchA) is a rare anomalous vessel that perfuses the posteromedial aspects of the cerebrum in place of the posterior cerebral artery. We describe 3 cases of hyperplastic AchA found among 61 patients with AchA aneurysms who underwent surgical or endovascular treatment at our institution. Case Presentation: All 3 cases were diagnosed as hyperplastic AchA type 2 according to the Takahashi classification, indicating an anomalous branching temporal artery perfusing the medial temporal lobe. We performed coil embolization for 2 cases and surgical clipping for the third. One embolization case experienced recurrence after 3 years and underwent clipping. All procedures were conducted without complications. Conclusion: Hyperplastic AchA can be encountered during aneurysm treatment. These cases emphasize the importance of evaluating the vascular anatomy to determine the optimal treatment strategy.
