Low-angled microcatheter approach for coil embolization of the anterior choroidal artery aneurysm.
Article in Neuroradiology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
purposeThromboembolic complication is a serious concern following coil embolization for aneurysms involving the anterior choroidal artery (AChA). To minimize this complication and to improve packing density, we present a technical concept of coil embolization.
methodsWe attempted packing of the aneurysmal sac by lowering the microcatheter approach angle into an aneurysm to secure AChA origin as well as to improve coil packing density of the aneurysm. This technical concept involves approaching the aneurysm sac with an adjusted shaping of the microcatheter tip to achieve the effect which was not obtained when the microcatheter approach angle into the aneurysm sac was high (≥90°). We evaluated immediate angiographic outcome by the Raymond classification, coil packing density, and follow-up results (modified Rankin Scale (mRS) and recurrence) in seven aneurysms involving AChA in six patients.
resultsWe achieved immediate angiographic outcome of the Raymond classes I or II with 31% mean packing density. The AChA origin was preserved without any procedure-related complication. There was neither clinical event (mRS = 0) nor aneurysm recurrence confirmed on the source image of magnetic resonance angiography during 6-9 months follow-up.
conclusionsThe technical concept of low-angled microcatheter approach can be useful to improve coil packing density and to secure AChA origin when AChA arises near the aneurysm.
