Comparison of EndoSuture vs fenestrated aortic aneurysm repair in treatment of abdominal aortic aneurysms with unfavorable neck anatomy.
Article in Journal of vascular surgery, 2025. 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
backgroundHostile aortic neck anatomy is associated with loss of proximal seal and increased late reinterventions. Although both EndoSuture aneurysm repair (ESAR) and fenestrated endovascular aortic repair (FEVAR) are commercially available options for treatment of short neck aneurysms, branch vessel patency is a potential tradeoff for improved seal with FEVAR owing to the incorporation of renovisceral vessels. This study compares the performance of ESAR vs FEVAR in hostile aortic necks.
methodsPatients who underwent elective ESAR or FEVAR for hostile neck AAAs at a single center from 2012 to 2024 were reviewed retrospectively. Exclusion criteria included pararenal or thoracoabdominal aortic aneurysm, off-label modifications, and nonstandard FEVAR configurations. Propensity matching weights were generated based on age, year of operation, preoperative estimated glomerular filtration rate, neck length, neck diameter, and infrarenal angulation. Rates of survival, reintervention, dialysis, chronic kidney disease stage progression, type IA endoleak (EL), and sac regression (>5 mm) were assessed at latest follow-up.
resultsOf 391 patients, 60 with ESAR and 207 with FEVAR were included. FEVAR patients were younger (74.4 years vs 79.8 years; P < .001) with larger neck diameters (25.0 mm vs 23.6 mm; P = .016), shorter neck length (5.0 mm vs 9.8 mm; P < .001), and decreased infrarenal angulation (20° vs 40°; P < .001). After propensity score-adjusted regression (58 ESAR, 169 FEVAR), FEVAR, compared with ESAR, was associated with decreased IA EL (hazard ratio, 0.341; 95% confidence interval [CI], 0.061-0.72; P = .031) and increased sac regression (hazard ratio, 3.92; 95% CI, 1.25-5.14; P = .02). Notably, FEVAR was associated with increased 1-year aneurysm-related reintervention (odds ratio, 4.33; 95% CI, 1.12-10.54; P = .046). On Kaplan-Meier analysis, FEVAR was associated with reduced freedom from reinterventions at 3 years (71.8% [95% CI, 0.63-0.78] vs 93.5% [95% CI, 0.80-0.97]; log-rank P = .019) but a trend toward improved survival at 3 years (79.15% [95% CI, 0.70-0.85] vs 61.5% [95% CI, 0.44-0.74]; log-rank P = .095). There was no significant difference in new-onset chronic dialysis between ESAR and FEVAR at 3 years (94.2% [95% CI, 0.82-0.98] vs 97.4% [95% CI, 0.93-0.99]; log-rank P = .124).
conclusionsIn the treatment of abdominal aortic aneurysms with hostile neck anatomy in this propensity-matched cohort, FEVAR was associated with fewer type IA ELs and greater sac regression compared with ESAR, with no detrimental impact on long-term renal function. There were more reinterventions, mostly branch related, in the FEVAR group. We await the results of the current randomized prospective trial comparing these strategies to further determine the impact of these clinical differences on aneurysm-related mortality.
