Acute Mesenteric Ischemia Following Cardiovascular Surgery - A Nested Case-Control Study.

•This study focusses on acute mesenteric ischemia following cardiovascular surgery.•Preoperative versus perioperative risk factors were compared to predict mesenteric ischemia.•Early postoperative parameters are superior to facilitate early diagnosis of mesenteric ischemia.•Liver cirrhosis and emergency operation remain preoperative key factors.•Serum lactate and use of catecholamines are most important perioperative indicators.
