Innominate artery versus combined innominate and femoral artery perfusion in acute type A aortic dissection: a comparison of surgical efficiency and early outcomes.

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
Objective: This study aimed to compare the impact of isolated innominate artery antegrade perfusion (IA) versus combined innominate and femoral artery perfusion (IA + FA) on surgical efficiency and short-term outcomes in patients undergoing surgery for acute type A aortic dissection (ATAAD). Methods: A single-center, retrospective cohort study was conducted involving 94 consecutive ATAAD patients who underwent surgery between May 2024 and May 2025. Patients were allocated into two groups based on the perfusion strategy: the IA group ( Results: The two groups were well-balanced in terms of baseline demographics and preoperative risk profiles. The total operative time was significantly shorter in the IA group compared to the IA + FA group (370.05 ± 63.34 min vs. 397.26 ± 62.11 min, Conclusion: For ATAAD surgery, an isolated innominate artery antegrade perfusion strategy significantly improves surgical efficiency by reducing operative time without compromising early safety outcomes, compared to a combined IA + FA approach. The routine addition of femoral artery perfusion did not confer measurable clinical benefits in this cohort. Thus, IA should be considered as a streamlined and efficient first-line perfusion strategy, potentially reserving IA + FA for select cases with specific indications. These findings warrant further validation in larger, prospective studies.
