Abstract

Objective Acute mesenteric ischemia (AMI) remains difficult to diagnose, carries a high rate of complications, and is associated with significant mortality. We evaluated our experience with AMI over the last 2 decades to evaluate changes in management and assess current outcomes.Methods Data from consecutive patients who underwent arterial revascularization for AMI over a 20-year period (January 1990-January 2010) were retrospectively reviewed. Patient demographics, treatment modalities, and outcomes over the last decade (2000-2010) were compared with those of the preceding decade (1990-1999) previously reported.Results Over the last 2 decades, 93 patients with AMI underwent emergency arterial revascularization. Forty-five patients were treated during the 1990s and 48 during the 2000s. The majority of these patients were transferred from outside facilities. Patient demographics and risk factors were similar between the 2 decades with the exception that the more contemporary patients were significantly older (65.1 ± 14 vs 71.3 ± 14; P = .04). Etiology remained constant between the groups with in situ thrombosis being the most common followed by arterial embolus. The majority of patients were treated with open revascularization. Endovascular therapy alone or as a hybrid procedure was used in 11 total patients, eight of which were treated in the last 10 years. The use of second-look laparotomy was much more liberal in the last decade (80% vs 48%; P = .003) Thirty-day mortality was 27% in the 1990s and 17% during the 2000s (P = 0.28). Major adverse events occurred in 47% of patients with no difference between decades. There was no significant difference in outcomes between open and endovascular revascularization. On univariate analysis, elevated SVS comorbidity score, congestive heart failure, and chronic kidney disease predicted early death, while a history of chronic mesenteric ischemia appeared protective. On multivariate analysis, no factor independently predicted perioperative mortality. Bowel resection and cerebrovascular disease predicted postoperative morbidity, while advanced age and connective tissue disease predicted long-term mortality.Conclusions Morbidity and mortality from AMI continues to be high. Revascularization by endovascular means, although more frequent in the last decade, was still utilized in a minority of patients with severe AMI. Advanced ischemia with bowel infarction at presentation, and markers of generalized atherosclerosis are predictors of poor outcome, while history of chronic mesenteric ischemia is associated with better outcome.

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.

  • Recent-cohort early-death counts disagree

    Major

    Table V lists nine early deaths in the 2000-2010 cohort, whereas the outcomes table lists eight 30-day deaths for that cohort.

  • Recent-cohort kidney-disease counts conflict

    Major

    Table V accounts for only two patients with chronic kidney disease across its early-death groups, while Table I reports nine in the 2000-2010 cohort. This discrepancy affects a factor reported as associated with early death.

  • Major-complication event count disagrees between tables

    Minor

    Table V labels 29 recent-cohort patients as having a major postoperative complication; Table IV reports 21 for the same cohort. Table V's no-event and event counts also total 56, exceeding the cohort's 48 patients.

  • Thrombosis total differs from the decade counts

    Minor

    The reported total is 50 patients, but the two decade-specific counts are 25 and 24, totaling 49.

  • Diabetes percentage is incorrect for the recent cohort

    Minor

    The table lists 13 patients with diabetes among 48 treated in 2000-2010. That is 27%, not the reported 20%.

    Reported 20 · recomputed 27.083333

  • Follow-up period switches from years to months

    Minor

    The prose gives the earlier cohort's mean follow-up as 2.9 months, but Table I labels that same value as years.

  • Late-death causes leave one death unaccounted for

    Minor

    The paper reports 36 late deaths, but 22 deaths of unknown cause plus the 13 deaths assigned known causes account for only 35.

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.
