Acute reperfusion therapy via occluded vertebral artery using a guiding sheath for posterior circulation tandem occlusion: illustrative case.

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
backgroundVertebral artery (VA) size, anatomy, and occlusion status should be considered when selecting endovascular access for basilar artery mechanical thrombectomy. In a patient with concomitant basilar artery and VA occlusion and a patent but hypoplastic contralateral VA, the occluded VA should be selected. The authors report a technique that utilizes advancing a guiding sheath with attached dilator via an occluded VA. OBSERVATIONS: A 65-year-old male presented with disturbed consciousness because of an acute infarction of the brainstem and cerebellum caused by a basilar artery occlusion. Cerebral angiography showed a hypoplastic right VA and occlusion of the left VA at the origin. A regular wire was easily advanced through the occlusion and a 4-Fr diagnostic catheter was advanced into the distal left VA. A 6-Fr guiding sheath with attached dilator was placed in the left VA beyond the occlusion by exchanging it over a long wire. After removing the basilar artery thrombus, balloon angioplasty was performed at the left VA origin. Complete revascularization of the posterior circulation was achieved. LESSONS: A guiding sheath with dilator can advance across and dilate a VA occlusion at the origin to provide rapid access to the basilar artery.
