Acute mesenteric ischemia (AMI) is a disease that causes an ischemia in the intestines due to the obstruction of the mesenteric vessels feeding the intestines, with a mortality rate reaching up to 80%. The overall incidence of AMI is 0.63 per 100,000 people. Early diagnosis and treatment are very important for survival. There is no ideal biomarker that can reflect different types and stages of AMI. This study investigated the predictive and prognostic value of L-lactate, D-dimer, leukocyte, C reactive protein (CRP) and neutrophil/lymphocyte ratio (NLR) in the preoperative period were investigated in patients operated for AMI.
