Stent-Assisted Coiling for a Ruptured Wide-Neck Basilar Artery Trunk Aneurysm With Preservation of Brainstem Perforators: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Basilar artery trunk aneurysms are rare, accounting for 2.1% of all intracranial aneurysms. Among these, Mizutani type 4 (nonbranching true aneurysms) carries a particularly high risk of rupture and rebleeding. Although endovascular therapy is common, reports on the safety and efficacy of stent-assisted coiling (SAC) for ruptured wide-neck basilar artery trunk aneurysms in the acute phase remain limited. A 60-year-old man presented with subarachnoid hemorrhage (World Federation of Neurosurgical Societies grade I). Imaging revealed a wide-neck saccular aneurysm (4.8 mm dome diameter, 5.4 mm neck width) in the basilar artery trunk, consistent with a Mizutani type 4 aneurysm. On day 2, SAC was performed using a Neuroform Atlas stent. Because the patient required no additional invasive procedures like external ventricular drainage, dual antiplatelet therapy (DAPT) was initiated immediately before the procedure. Complete occlusion was achieved while maintaining the patency of the brainstem perforators. The patient was discharged with a modified Rankin Scale score of 0, and stable occlusion was maintained at the three-month follow-up. In conclusion, SAC using the Neuroform Atlas stent on DAPT is a viable treatment option for ruptured wide-neck basilar artery trunk aneurysms. This approach allows for secure aneurysm occlusion while minimizing the risk of ischemic complications in the perforator-rich basilar trunk.
