Abstract

Objectives Few centers have adopted endovascular therapy for the treatment of acute mesenteric ischemia (AMI). We sought to evaluate the effect of endovascular therapy on outcomes for the treatment of AMI.Methods A single-center, retrospective cohort review was performed on all consecutive patients with thrombotic or embolic AMI presenting between 1999 and 2008. Patients with mesenteric venous thrombosis, nonocclusive mesenteric ischemia, and ischemia associated with aortic dissection were excluded. Demographic factors, preoperative metabolic status, and etiology were compared. Primary clinical outcomes included endovascular technical success, operative complications, and in-hospital mortality.Results Seventy consecutive patients were identified with AMI (mean age, 64 ± 13 years). Etiology of mesenteric ischemia was 65% thrombotic and 35% embolic occlusions. Endovascular revascularization was the preferred treatment (81%) vs operative therapy (19%). Successful endovascular treatment was achieved in 87%. Endovascular therapy required laparotomy in 69% vs traditional therapy in 100% (P < .05), with a median 52-cm necrotic bowel resected (interquartile range [IQR], 11-140 cm) vs 160 cm (IQR, 90-250 cm; P < .05), respectively. Acute renal failure and pulmonary failure occurred less frequently with endovascular therapy (27% vs 50%; P < .05 and 27% vs 64%; P < .05). Successful endovascular treatment resulted in a mortality rate of 36% compared with 50% (P < .05) with traditional therapy, whereas the mortality rate for endovascular failures was 50%. Endovascular therapy was associated with improved mortality in thrombotic AMI (odds ratio, 0.10; 95% confidence interval, 0.10-0.76; P < .05).Conclusions Endovascular therapy has altered the management of AMI, and there are measurable advantages to this approach. Using endovascular therapy as the primary modality for AMI reduces complications and improves outcomes.

  • Arthurs et al. reported that 56 of 70 patients with acute mesenteric ischemia underwent initial endovascular treatment, with a high success rate and lower in-hospital mortality compared with open surgery (36% vs 50%; P < .05).

    “a recent single-institution publication from the Cleveland Clinic by Arthurs et al 4 in which 56 of 70 patients with AMI underwent initial endovascular treatment.The group demonstrated a high success rate with only nine of 56 treatment failures and a lower in-hospital mortality rate with endovascular treatment of AMI compared to traditional open surgical treatment (36% vs 50%; P Ͻ .05).”

  • Endovascular therapy for acute mesenteric ischemia has escalated dramatically at most institutions and has been associated with lower mortality than traditional open surgery.

    “Over the last decade, the use of endovascular therapy for treatment of patients with AMI has escalated dramatically at most institutions and has been associated with lower mortality than traditional open surgical therapy.4,5”

    From Revascularization for acute mesenteric ischemia (2012) · cites this paper as [4]

  • The higher mortality of arteriosclerotic occlusions compared to embolic occlusions is probably due to a larger and more poorly compensated bowel ischemia.

    “Moreover, arteriosclerotic occlusions were associated with higher mortality compared to embolic occlusions (53% vs. 34%; P = 0.11), probably due to a larger and more poorly compensated bowel ischemia [1, 11].”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Renal-failure significance differs between abstract and table

    Major

    The abstract reports P < .05 for the 27% versus 50% acute renal failure comparison, while Table III reports P = .14 for the same comparison.

  • Overall mortality comparison has two P values

    Minor

    The Results text gives P = .10 for the 39% versus 50% mortality comparison, whereas Table III gives P = .15.

  • Confidence-interval lower bounds differ

    Minor

    For the thrombotic AMI mortality odds ratio of 0.10, the abstract gives a confidence-interval lower bound of 0.10, but the Results section gives 0.17. The latter interval also excludes the reported point estimate.

  • Lytic-therapy count and percentage disagree

    Minor

    The discussion says 28 of 56 endovascular patients received lytic therapy. That is 50%, not the stated 48%.

    Reported 48 · recomputed 50

  • Extended-infusion count conflicts with duration percentages

    Minor

    The Results section says 36% received two days of infusion and 5% received three days-about 11 of the approximately 27-28 lytic-therapy patients. The discussion instead says about seven received two or more days.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-01.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-01.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
