1 · What the graph read from it

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.

2 · The registry

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

backgroundWe innovatively modified Sun's procedure by substituting the distal frozen elephant trunk (FET) stent with an intraoperative single-branch stent and employing the adventitial inversion technique at the proximal anastomosis. This study aims to evaluate the perioperative efficacy and short-term outcomes associated with this modified procedure.

methodFrom January 2019 to December 2024, 147 consecutive patients with acute type A aortic dissection underwent surgery. Of these, 73 patients had ascending aorta and total arch replacement with distal stent grafting. Patients were divided into two groups based on surgical technique: Group A (n = 41) received proximal adventitial inversion technique with distal single-branch stent implantation, while Group B (n = 32) underwent Sun's procedure. Comparative analysis of preoperative characteristics, intraoperative parameters, and postoperative outcomes was performed.

resultsThe groups demonstrated comparable preoperative characteristics. Intraoperatively, the modified technique achieved 39.8% shorter total operation time (median 320 vs. 532.5 min; P < 0.001) with 38.1% reduction in cardiopulmonary bypass (CPB) time (151.3 ± 2.6 vs. 244.3 ± 6.9 min; P < 0.001). This technical modification translated to 65% lower blood product requirements (median red blood cells units: 2 vs. 6; total transfusion volume: 920 vs. 2640 mL; P < 0.001). Postoperatively, Group A exhibited 87.9% shorter mechanical ventilation duration (13.5 vs. 111.5 h; P < 0.001) and 64.7% reduced ICU stay duration (3 vs. 8.5 days; P < 0.001), alongside 63.5% lower composite complication rate (17.1% vs. 46.9%; P = 0.006). Notably, A trend towards reduction in postoperative cardiogenic shock (0% vs. 12.5%; P = 0.070) and surgical re-exploration for bleeding (0% vs. 3.1%; P = 0.438) was observed in Group A. Critically, both techniques demonstrated equivalent in-hospital mortality (4.9% vs. 6.3%; P = 1.000).

conclusionOur modified technique demonstrates comparable safety to Sun's procedure while offering superior operative efficiency and reduced postoperative morbidity in Acute type A aortic dissection (ATAAD) repair. These findings support broader clinical application of this innovative approach.
