Condition: Acute Mesenteric Ischemia · Sponsor: Assistance Publique Hopitaux De Marseille
Acute mesenteric ischemia (AMI) is associated with high mortality (50-80%). The prognosis depends on the time it takes to diagnose the condition, and the possibility of revascularization in eligible patients. Delayed diagnosis is due in particular to the aspecific clinical presentation and the absence of biomarkers to guide early diagnosis, lactates often being elevated at an already irreversible stage. Adenosine deaminase is produced in the presence of ischemia (known from myocardial ischemia), and is present on the surface of intestinal villi. The investigator's hypothesis is that, in the event of digestive ischemia resulting in abnormalities of mesenteric permeability, adenosine deaminase will enter the bloodstream and increase its soluble plasma activity, along with an increase in lymphocyte-bound adenosine deaminase. The main objective is to evaluate the discriminatory capacities of soluble adenosine deaminase, collected via blood sampling, for the diagnosis of IMA in comparison with the reference method (injected abdominopelvic CT scan), performed for abdominal pain suggestive of IMA. The study will be based on a prospective monocentric cohort. Currently, there is no specific biological marker for IMA, and the gold standard for diagnosis is the injected abdominopelvic CT scan, performed for hyperintense abdominal pain. Two groups will be identified on the basis of the gold-standard abdominopelvic scan: * the "IMA patients" group: patients with hyperintense abdominal…
