Optimal Management of Isolated Left Vertebral Artery in Total Arch Replacement With Frozen Elephant Trunk for Aortic Dissection.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe presence of an isolated left vertebral artery (ILVA) in patients with aortic dissection is a rare and challenging condition. This study aims to determine the optimal management of ILVA in patients with aortic dissection undergoing total arch replacement with frozen elephant trunk.
methodsThis retrospective study enrolled 94 patients with ILVA and aortic dissection who underwent total arch replacement with frozen elephant trunk. Patients were divided into 3 groups: 18 patients underwent ligation of ILVA, 52 underwent ILVA-left subclavian artery transposition, and 24 underwent ILVA-left common carotid artery transposition.
resultsVertebral artery dominance was left dominant in 10.6%, symmetric in 33.0%, and right dominant in 56.4% of patients. Notably, patients who underwent ligation of ILVA had either symmetric or right-dominant vertebral arteries, with no left-dominant cases. No strokes were observed. Paraplegia/paraparesis (11.1% versus 11.5% versus 0%,
conclusionsLigation of ILVA, ILVA-left subclavian artery transposition, and ILVA-left common carotid artery transposition are all feasible and safe strategies for managing ILVA in patients with aortic dissection undergoing total arch replacement with frozen elephant trunk.
