Total Aortic Arch Replacement With the Frozen Elephant Trunk Technique: Influence of Aortic Arch Anomalies.
Article in Interdisciplinary cardiovascular and thoracic surgery, 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
objectivesTo assess surgical challenges and outcomes associated with arch anomalies in patients undergoing frozen elephant trunk (FET) for acute and chronic dissections.
methodsFrom January 2007 to January 2024, 401 patients underwent FET procedure in our centre. We included 285 patients with acute type A/B, chronic type A/B, and residual dissection. Patients were divided into normal arch group (n = 216) and arch anomalies group (n = 69), including aberrant right subclavian artery, bovine trunk, arch vertebral artery, and gothic arch.
resultsOverall in-hospital mortality was 15.4% (17.4% in arch anomalies vs 14.8% in arch normal). In-hospital thoracic endovascular aortic repair (TEVAR) occurred in 7.2% (n = 5) of patients with arch anomalies. Stent graft-induced new entry tear at follow-up was 26.1% in arch anomalies vs 17.1% in arch normal group. Long-term survival in the overall patients was not different between the 2 groups (P = .383). In the subgroup of patients treated for chronic aortic dissection, freedom from TEVAR was higher in those with normal arch anatomy (P = .026).
conclusionsAortic arch anomalies, especially in chronic dissection, were associated with increased endovascular reintervention. The gothic arch is the most challenging configuration due to frequent stent kinking.
