Outcomes of thoracic endovascular aortic repair for blunt thoracic aortic injury with emphasis on short proximal sealing zones ≤ 15 mm.
Article in CVIR endovascular, 2026. 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
purposeBlunt thoracic aortic injury (BTAI) is the second leading cause of mortality in patients with trauma, closely following head injuries, which remain a significant concern in trauma care. Thoracic endovascular aortic repair (TEVAR) is the preferred treatment for BTAI; however, insufficient proximal sealing zone length poses a significant challenge for successful TEVAR. This study aimed to investigate the outcomes of TEVAR in patients with BTAI, including those with short proximal sealing zones (≤ 15 mm). MATERIALS AND
methodsThis retrospective study included 52 consecutive patients who underwent TEVAR for BTAI in the authors' institution between January 2018 and December 2023. Patient demographics, BTAI grade, adverse events, and endoleak were assessed. Proximal sealing zone length was measured on pre-procedural computed tomography (CT). Subgroup analysis was used to compare outcomes between patients with proximal sealing zones ≤ 15 and > 15 mm.
resultsThe average injury severity score was 44.1 ± 15.8, with 88.5% of patients sustaining grade 3 BTAI. One technical failure occurred owing to an acute aortic arch angle. A total of 29 patients had proximal sealing zones ≤ 15 mm, with 5 of them undergoing left subclavian artery coverage. Endoleak occurred in three patients (5.9%), resulting in the death of one patient. The remaining two patients had suspected type 4 endoleaks that resolved on follow-up CT. No significant differences were observed in aortic-related mortality and endoleak between the two groups.
conclusionsTEVAR is an effective treatment option for BTAI, even in patients with short proximal sealing zones ≤ 15 mm.
