The goal of this retrospective observational study is to describe the incidence and outcome of patients diagnosed with acute mesenteric ischemia (AMI) in the Västra Götaland region of Sweden between 2000-2023. The main questions it aims to answer are:
* What was the observed incidence and outcome, and how did it change during the time period?
* How did socioeconomic factors influence incidence and outcome of AMI?
* What main surgical approaches were selected for these patients?
* What was the distribution of anticoagulant use in the cohort, and what effect did the introduction of new oral anticoagulants (NOAC) have on incidence and mortality in AMI?
* What was the prevalence of Short Bowel Syndrome (SBS) after surgical intervention?
Participants were obtained from the regional diagnosis registry. Additional datapoints were obtained from the Swedish statistics bureau and pharmaceutical registers.
