Safety and efficacy of the neuroform EZ stent for treating intracranial atherosclerotic stenosis in the posterior circulation: a comparative study of pre-procedure and post-procedure outcomes.
Article in Langenbeck's archives of surgery, 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
backgroundTreatment options for intracranial atherosclerotic stenosis (ICAS) are limited, but endovascular intervention has gained increasing attention in recent years.
aimTo evaluate the safety and efficacy of the Neuroform EZ stent for treating ICAS in the posterior circulation. MATERIAL &
methodsPatients' (n = 50) eligibility depended on ICAS with severe stenosis (≥ 70%) in the intracranial segment of the vertebral artery or basilar artery shown by cerebral angiography. General information of the participants were recorded, Adverse events during the perioperative period were observed, including in-stent thrombosis, postoperative hyperperfusion, stroke, and mortality. Before the procedure, neurological deficits (NIHSS score) and neurological recovery (mRS score) were recorded at 12 months postoperatively. The degree of vascular stenosis was evaluated prior to and following the procedure, and in-stent restenosis (ISR) was recorded at 12 months post-operation.
resultsFifty-two stents were successfully placed in 50 patients, followed by standardized medication. Angiographic follow-up was completed 12-months postoperatively, and there was only one case of ISR (4.35%) was observed. Postoperative stenosis of responsible vessel was significantly relieved (77.98 ± 7.69 vs. 33.85 ± 9.11), with statistically significant differences (P < 0.01). The extent of neurological deficits and effects on daily living activities at 12 months postoperatively exhibited significant improvements, as evidenced by NIHSS scores (2.40 ± 1.37 vs. 0.82 ± 0.77) and mRS scores ≤ 2 (82.0% vs. 98.0%) (P < 0.01). Cerebral perfusion improved, with no significant perioperative complications.
conclusionsThe Neuroform EZ stent is a safe and effective treatment approach for ICAS in the posterior circulation.
