Three-dimensional simulations for planning fenestrated/branched endografts in endovascular aneurysm repair for complex abdominal aortic aneurysm: 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
backgroundEndovascular aneurysm repair (EVAR) is used to treat patients with abdominal aortic aneurysm (AAA) who have suitable anatomy, while complex AAAs often require fenestrated and branched stent grafts, necessitating further refinement of the technique.
objectiveTo evaluate the safety and efficacy of fenestrated/branched EVAR (F/B-EVAR) assisted by three-dimensional (3D) printing for treating complex AAA.
designRetrospective cohort study.
methodsThis multicenter retrospective cohort study collected baseline data and clinical outcomes from patients treated with F/B-EVAR between January 2012 and June 2025. The population was divided into the 3D simulation group and the conventional measurement group. The 3D simulation group underwent a simulation to assess fenestration and branch positioning strategies. Study endpoints included procedural success rate, incidence of periprocedural complications and major adverse events, as well as procedural duration and radiation dose.
resultsThe mean age of patients was 70.2 ± 8.8 years, with 68.9% being male. Compared to the conventional measurement group, the 3D simulation group had a significantly higher procedural success rate (98.8% vs 91.6%,
conclusionF/B-EVAR guided by 3D simulation may allow for accurate planning of fenestration and branch positioning, potentially improving procedural success rate and suggesting a potential to enhance the quality of outcomes.
