Endovascular repair of type B acute aortic syndromes involving the left subclavian artery: A retrospective single-centre study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 mid-term outcomes of using the Castor single branched stent graft to treat patients with type B acute aortic syndromes (AASs) involving the left subclavian artery (LSA) were unclear. This study aims to evaluate the mid-term efficacy of the Castor single branched stent graft in the treatment of type B AASs involving the LSA.
methodsThe retrospective study enrolled patients with type B AASs involving the LSA who were consecutively admitted to our hospital between January 1, 2019 and October 30, 2023. Patients underwent thoracic endovascular aortic repair (TEVAR) using the Castor device. The clinical data of these patients were collected, and their outcomes were followed.
resultsThis study included 106 patients, comprising those presenting with aortic dissection (AD) (n = 93), penetrating aortic ulcer (PAU) (n = 9), and intramural haematoma (IMH) (n = 4). All patients achieved the technical success. After a median follow-up period of 454 days (range: 359-771 days), all patients demonstrated survival, with 14 (14.4%) patients experiencing complications, including acute myocardial infarction (AMI, n = 1), endoleaks (n = 7), stenosis of the branched section(n = 3), stent graft-induced new entry tear (SINE, n = 2), and progressive aortic dilation (n = 1). Among the endoleaks, there were 1 Type Ib, 2 Type II, and 4 Type IV cases. Among the enrolled patients, two required re-intervention. No retrograde type A aortic dissection (RTAD), paraplegia or stroke were observed during the follow-up period.
conclusionThe Castor device provided an easily manipulated, safe, and effective treatment option for patients with type B AASs involving the LSA.
