Stent placement as rescue treatment in acute basilar artery occlusion.
Observational study in Journal of neurology, 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
introductionWe investigated the etiology, safety and efficacy of endovascular treatment with and without stent placement as rescue treatment in patients with acute ischemic stroke due to basilar artery occlusion (BAO).
methodsA Single-center retrospective observational study in consecutive patients with BAO treated with endovascular procedures, divided into stent and non-stent groups. Outcomes of interest were: stroke etiology; recanalization of the basilar artery defined as mTICI ≥ 2b; any intracranial hemorrhage; poor functional outcome (mRS 4-6) at 3 months. Independent associations were investigated with multivariable logistic and ordinal regression analyses adjusted for age, sex, NIHSS, rt-PA use and time-to-groin.
resultsThe analysis included 121 patients with a mean age of 70 (± 14) years; 48 (40%) were female. The median NIHSS score was 14 (IQR 6-36). Stent placement was performed in 28 patients (23%), mainly in those with atherosclerosis and artery dissection. Recanalization occurred in 110 (91%) patients, 79% in the stent group patients and 94% in the non-stent group. Ordinal analysis demonstrated higher risk of worse outcome in the stent group (OR = 3.73; 95%CI = 1.46-9.57); however, all patients without vessel recanalization had poor functional outcome. Periprocedural complications, particularly vessel perforation (14% vs 2%, p < 0.001), were more frequent in the stent group, whereas intracranial hemorrhage was similar between groups (7% vs 2%, p = 0.200).
conclusionsStent placement was more frequent in patients with stroke due to atherosclerosis or artery dissection and was associated with higher rates of procedural complications and poor functional outcome. However, stenting represents an acceptable option for rescue therapy in BAO due to the high burden of disease in patients who did not achieve vessel recanalization.
