Acute kidney injury and aorta-related mortality during open surgery of the abdominal aorta with suprarenal clamping using different renal protection strategies.
Observational study in European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
objectivesThe aim was to evaluate the incidence of acute kidney injury in patients treated with open surgical repair and suprarenal cross-clamp comparing no-perfusion strategy versus the renal perfusion with the histidine-tryptophan-ketoglutarate solution.
methodsIt is a physician-initiated, multicentre, retrospective observational study including patients treated with open surgical repair for abdominal aortic aneurysm between 1 January 2015 and 31 December 2021. Patients already on dialysis were excluded from the final analysis. A coarsened exact match identified 2 cohorts: no-perfusion strategy versus renal perfusion with the histidine-tryptophan-ketoglutarate solution. Primary outcomes were acute kidney injury incidence and survival at 30 day. Secondary outcomes were freedom from haemodialysis and survival at 1 year.
resultsWe analysed 125 (28.7%) patients: 63 (14.5%) who did not receive renal perfusion and 62 (14.2%) who received the histidine-tryptophan-ketoglutarate perfusion. At 30 day, acute kidney injury rate (37.6%) was not different between the 2 groups [n = 24 (38.7%) vs 23 (36.5%); OR: 1.1, P = 0.855]. At 30 day, acute kidney injury development was associated with aneurysm extent (pararenal, OR: 2.28, 95% CI: 1.031-5.031, P = 0.042) and total time of intervention (threshold: 365 min, OR: 1.008, 95% CI: 1.003-1.012, P = 0.001). At 1 year, postoperative acute kidney injury did not impact mortality (OR: 3.4, P = 0.556), and freedom from haemodialysis was 100%.
conclusionsPostoperative acute kidney injury remains high at nearly 38%, but it did not impact on freedom from haemodialysis at 1 year as well as on overall survival.
