Bailout Renal Stenting Associated With Endovascular Aortic Repair: A Single Centre Experience.
Article in EJVES vascular forum, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: This study describes the midterm results of renal stenting as a bailout technique during endovascular aortic repair (EVAR) of abdominal aortic aneurysms. Method: A single centre retrospective study of renal artery rescue procedures during consecutive elective EVARs was performed in patients without pre-existing renal stenosis over a 22 year period. Demographic characteristics, aneurysm neck morphometry surgical details, technical success, peri-operative complications, re-interventions, renal function, and death during follow up were analysed. Results: Seven renal stents were implanted (all men; mean age 72.3 ± 7 years) in 748 EVARs (0.9%) in the study period. Two of seven (29%) patients had chronic kidney disease before the intervention. Two of seven (29%) aortic necks fulfilled hostility criteria (one case of conical neck and one case with a diameter >28 mm at renal level). The Herculink Elite (Abbott, Chicago, IL, USA) stent was used in all patients (seven of seven) (median length 18 mm, median diameter 6.14 ± 0.7 mm). Technical success was 100%, with no complications associated with the renal stenting and no peri-operative death. The two patients with chronic kidney disease presented with worsened renal function (creatinine 2.72 ± 3 mg/dL, glomerular filtration rate 62.3 ± 32) a median 17 months after the intervention, with no renal replacement therapy requirements during follow up. The renal stent patency rate was 100% after a median follow up of 21 months (range 6-92 months); no cases of renal infarction were identified on follow up imaging. Conclusion: The need for bailout renal stenting during EVAR was low in this cohort. It is essential to adopt all measures that guarantee precise endograft deployment, even in favourable anatomies.
