Impact of aetiology on short- and long-term outcomes in open descending and thoracoabdominal aneurysm repair.

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
objectivesWe analysed the impact of chronic type B aortic dissection (cTBAD) and degenerative aneurysm (DA) on the short- and long-term outcomes of patients undergoing open descending thoracic aortic aneurysm and thoracoabdominal aortic aneurysm repair.
methodsWe performed a retrospective analysis of a prospectively maintained aortic database. From 1999 to 2023, 245 patients underwent open descending thoracic aortic aneurysm or thoracoabdominal aortic aneurysm repair. We compared preoperative comorbidities, postoperative complications and operative and long-term mortality for patients with cTBAD (120 patients, 49%) and DA (125 patients, 51%).
resultsPatients with cTBAD were significantly younger, more likely to be male and less likely to have comorbidities including diabetes, chronic obstructive pulmonary disease and coronary artery disease. There were no statistically significant differences in the incidence of operative mortality between cTBAD (7.5%) and DA patients (11.2%) (P = 0.44). Survival at 1, 5, 10 and 15 years for cTBAD versus DA patients was 90% versus 76%, 79% versus 59%, 59% versus 42% and 50% versus 29%, respectively (P < 0.01); however, this lost statistical significance in the Cox regression (P = 0.86). Following multivariable analysis, older age, female gender, coronary artery disease, urgent or emergent procedure and descending thoracic aortic aneurysm were independent predictors of long-term outcomes.
conclusionsThere were no statistically significant differences in the incidence of postoperative complications, operative deaths and long-term survival between cTBAD and DA patients. IRB NUMBER: (#20D.802), Obtained: 1/31/23.
