Initial experiences of the Optima™ coil system in intracranial aneurysm treatment: surgical and interventional approach to safety and efficacy in terms of cerebral arteries.
Article in Acta cirurgica brasileira, 2025. 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
purposeTo evaluate the angiographic outcomes of the Optima™ coil system in the endovascular treatment of saccular intracranial aneurysms to present real-world experiences.
methodsThe study encompassed patients with both ruptured and unruptured aneurysms who underwent treatment with the Optima™ coil system. A retrospective analysis was conducted to examine patient and aneurysm characteristics, complication rates, and angiographic outcomes.
resultsThe total of 326 Optima™ coil implantations was performed in 64 aneurysms, with a mean maximum diameter of 7.49 ± 3.08 mm (range: 2.5-16.5 mm), among 64 patients (37 females and 27 males, mean age: 53.34 ± 14 years old). The average number of implanted coils was 5.06 ± 1.73. The mean packing density was 26.2% (range = 19.2-34.6), observed to be significantly higher in aneurysms with complete occlusion and neck remnants compared to those with a residual dome (p < 0.01). The mean follow-up period was 15.9 ± 8.1 months. One case (1.5%) reported a coil malfunction attributed to coil stretching. The mortality rate was 3.1% (n = 2).
conclusionThe Optima™ coil system exhibited safety and efficacy in the endovascular treatment of both ruptured and unruptured intracranial aneurysms, demonstrating favorable angiographic outcomes. Nevertheless, further studies are necessary to validate these results over the long term.
