Use of Target Tetra with an understanding of its novel structure.
Article in Surgical neurology international, 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
Background: Coil embolization for cerebral aneurysms is an important technique and is not likely to be replaced in the foreseeable future. Recently, the Target Tetra detachable coil (TTDC) has become available, thereby raising expectations for a safer embolization in small aneurysms. Based on our experience, we report the behavioral characteristics and effective utilization of TTDCs. Methods: We analyzed 28 patients who underwent surgery using the TTDC for intracranial aneurysms between December 2023 and November 2024. Results: Five cases were treated using the TTDC only. In four of five cases, the aneurysm height was <3 mm. In terms of complications, intraprocedural rupture occurred in two cases and thrombosis in two. None of the patients presented with delayed hemorrhage during the follow-up period. Conclusion: The TTDC coils cluster at the tip of the microcatheter. Thus, effective embolization can be achieved by filling from the deeper available space. Based on the behavioral characteristics of TTDCs, it is not only beneficial as a finishing coil but also plays a role in filling. We believe that TTDCs may be a useful option for embolizing small aneurysms, including ruptured ones that were previously challenging to treat, and cases in which microcatheter stability are compromised.
