The safety and prognostic evaluation of subsequent aortic surgery after thoracic endovascular aortic repair: a retrospective cohort study.

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
Background: Thoracic endovascular aortic repair (TEVAR) is a widely employed clinical procedure for treating various aortic pathologies. However, some patients require subsequent surgical interventions post-TEVAR, particularly due to life-threatening complications such as aortic dissection. This study aimed to evaluate the safety and prognosis associated with additional aortic surgeries following TEVAR. Methods: A retrospective analysis was conducted on 21 patients who underwent aortic surgery after TEVAR at Guangdong Provincial People's Hospital between September 2016 and August 2020. By compiling and reviewing perioperative data, we assessed surgical-related complications and survival rates. Results: Among the 21 patients, 95.2% were male, with an average age of 53 years. Preoperative comorbidities included hypertension in 15 individuals, abdominal aortic aneurysm in one patient, and coronary heart disease in two patients. The primary complications of TEVAR were stent leakage and retrograde aortic dissection, with the latter being the predominant type in subsequent aortic surgeries. The mean duration of aortic clamping during surgery was 130.0 minutes, with a deep hypothermic circulatory arrest time of 8.5 minutes. Postoperatively, two patients suffered in-hospital mortality, one developed renal dysfunction, four required re-entry into the operating room for further treatment, and the average length of hospital stay was 20 days. Following discharge, 14.3% of patients experienced complications, with central nervous system symptoms being the most prevalent. Kaplan-Meier survival analysis indicated a 5-year survival rate of 85.7%. Conclusions: Aortic surgical intervention following TEVAR is a safe therapeutic approach that can improve patient prognosis. However, meticulous management of the perioperative period is crucial for reducing the risk of complications and improving survival rates. This study provides valuable insights into aortic surgery post-TEVAR, but large-scale research is needed to validate these findings.
