Two-stage reconstructive overlapping stent LEO+ and SILK for treatment of intracranial circumferential fusiform aneurysms in the posterior circulation.
Article in Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Intracranial circumferential fusiform aneurysms of the posterior circulation involving arterial branches or perforating vessels are difficult to treat. This article shows an endovascular reconstruction technique not yet described, using a telescoping self-expandable stent (LEO+) and flow-diverter device (SILK) at different surgical times. Two patients with circumferential fusiform aneurysm, one being an aneurysm of the segments P2 and P3 of the posterior cerebral artery, diagnosed after a headache, and the other a partially thrombosed aneurysm of the lower basilar artery, diagnosed following ischemia of the brain stem. Endovascular treatment was performed by means of a vascular reconstruction technique that used at different surgical times: overlapping; a telescoped self-expandable stent, LEO+; and a flow-diverter device, SILK. Angiographic control was carried out at 6 and 12 months, to evaluate arterial patency, flow maintenance in the arterial branches and perforating vessels, and thrombosis of the aneurysm. The combined use at different surgical times of the self-expandable stent and flow-diverter device was technically successful in both patients. There were no complications during the procedure, nor in the long-term follow-up with full arterial vascular reconstruction, maintenance of cerebral perfusion and complete aneurysm occlusion at the 6- and 12-month angiographic follow-up. There was no aneurysm recanalization nor intra-stent stenosis. Circumferential fusiform aneurysm of the posterior circulation involving arterial branches or perforating vessels to the brain stem may be treated with this arterial reconstruction technique at different surgical times, using the self-expandable stent called LEO+ and the flow-diverter device SILK, minimizing the risk of complications and failure of the endovascular technique, with the potential for arterial reconstruction with thrombosis of the aneurysmatic sac, as well as flow maintenance in the eloquent arteries, in this type of cerebral aneurysm.
