Outcomes of Surgical Repair of Aberrant Subclavian Arteries in Adults.
Article in The Annals of thoracic surgery, 2024. 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
backgroundSymptoms, imaging characteristics, and early and midterm surgical outcomes for aberrant subclavian arteries (ASCA) are not well defined in the adult population.
methodsA single-institution retrospective review was conducted of adults undergoing surgical repair of ASCA and descending aorta origin/Kommerell diverticulum (KD) from January 1, 2002, to December 31, 2021. Symptom improvement and differences in imaging characteristics between anatomic groups and the number of symptoms were assessed.
resultsMean age was 46 ± 17 years. There were 23 of 37 left aortic arches with right ASCA (62%) and 14 of 37 right aortic arches with left ASCA (38%). Of these, 31 of 37 (84%) were symptomatic, and 19 of 37 (51%) had KD size/growth meeting criteria for surgical repair. KD aortic origin diameter was larger in more symptomatic patients: 20.60 mm (interquartile range [IQR], 16.42-30.68 mm) in patients with ≥3 symptoms vs 22.05 mm (IQR, 17.52-24.21 mm) for 2 symptoms vs 13.72 mm (IQR, 12.70-15.95 mm) for 1 symptom (P = .018). Aortic replacement was required in 22 of 37 (59%). There were no early deaths. Complications occurred in 11 of 37 (30%): vocal cord dysfunction (4 of 37 [11%]), chylothorax (3 of 37 [8%]), Horner syndrome (2 of 37 [5%]), spinal deficit (2 of 37 [5%]), stroke (1 of 37 [3%]), and temporary dialysis requirement (1 of 37 [3%]). Over a median follow-up of 2.3 years (IQR, 0.8-3.9 years), there was 1 endovascular reintervention and no reoperations. Dysphagia and shortness of breath resolved in 92% and 89%, respectively, whereas gastroesophageal reflux persisted in 47%.
conclusionsThe KD aortic origin diameter correlates with the number of symptoms, and surgical repair of ASCA and descending aorta origin/KD effectively relieves symptoms, with low rates of reintervention. Given the operative complexity, surgical repair should be performed in patients meeting size criteria or with significant dysphagia or shortness of breath symptoms.
