Mechanical Thrombectomy for Medium-Vessel Occlusion with a Right-Sided Aortic Arch: A Case Report.

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
Objective: A right-sided aortic arch is a rare vascular anomaly, and neuroendovascular therapy through the right-sided aortic arch is extremely rare. Herein, we report the case of a patient with a right-sided aortic arch who performed a mechanical thrombectomy for medium-vessel occlusion. Case Presentation: An 84-year-old woman could not respond to her family during a conversation at 8:50 am. She was brought to our hospital at 10:30 am on the same day. A diffusion-weighted image of head magnetic resonance imaging revealed a high-intensity area in the left temporal lobe. Head magnetic resonance angiography revealed a loss of the inferior trunk of the left middle cerebral artery. A mechanical thrombectomy was performed. The guiding catheter ascended on the right side from the midline, and the patient was considered to have a right-sided aortic arch. Selecting the left common carotid artery was difficult due to its unusual origin from the ascending aorta. Internal carotid angiography revealed left temporo-occipital artery occlusion. Mechanical thrombectomy was performed using Solitaire X 3× 20 mm (Covidien, Irvine, CA, USA), and recanalization was achieved. Contrast-enhanced chest and abdominal computed tomography revealed a right-sided aortic arch with an aberrant left subclavian artery. She was transferred to a recovery hospital with a modified Rankin Scale score of 1. Conclusion: Understanding the branching patterns and classifications of the right-sided aortic arch is necessary for physicians performing mechanical thrombectomy.
