Background Computed tomography (CT) can be used as the primary screening modality for the evaluation of patients suspected of having acute mesenteric ischemia known to show high sensitivity and specificity rates. Purpose To prove the value of CT in patients with pathological abdominal findings following cardiac surgery. Material and Methods In a retrospective case-control study, 12 different CT scan parameters of patients with or without mesenteric ischemia following cardiac surgery were compared using univariate and logistic regression analyses. Results Of 14,176 patients, 133 (0.9%) received an abdominal CT scan during postoperative care due to pathological abdominal findings. Sixty-eight patients were diagnosed with acute mesenteric ischemia. In-hospital mortality was 73.5% for this group. CT parameters with the highest specificity for indicating colonic ischemia were intestinal (99%) or porto-venous (96%) pneumatosis, abnormal contrast medium enhancement (89%), and occlusion of the proximal inferior mesenteric artery (81%). All of those parameters showed low sensitivity levels in the range of 15%–23%. A statistically significant association between acute mesenteric ischemia and CT appearance was obtained for contrast medium enhancement (odds ratio [OR] 12.2, 95% confidence interval [CI] 1.5–99.2) and intestinal pneumatosis (OR 21.0, 95% CI 2.7–165.2) only. Conclusion The typical CT criteria indicating mesenteric ischemia lose their accuracy in patients under critical clinical conditions. As CT remains the first-line diagnostic imaging modality for abnormal abdominal findings following cardiac surgery, negative signs should not prevent early laparotomy if clinical suspicion remains high.

Introduction. Acute mesenteric ischemia is a rare, but extremely severe life-threatening condition with a mortality rate of 40 to 60%, despite the development of modern high-tech diagnostic and treatment methods. Unfortunately, acute mesenteric ischemia does not have any pathognomonic symptoms or highly specific laboratory and instrumental symptoms and manifests as abdominal pain syndrome, which makes it harder to differentiate diagnosis and results in a delay in taking appropriate therapeutic measures.Clinical case. This clinical case report describes a case of a 70-year-old patient who was admitted to the cardiology department after undergoing percutaneous coronary intervention due to acute myocardial infarction. On the third day, the patient developed severe diffuse abdominal pain and diarrhea. After the series of diagnostic measures have been performed, an acute impairment of mesenteric circulation was suspected and a decision was made to perform spiral computed tomography, which confirmed the presence of a thrombus in the superior mesenteric artery. The patient underwent X-ray endovascular thrombospiration, transluminal balloon angioplasty and stenting of the superior mesenteric artery. Due to the persistence of abdominal pain on the following day, the patient also underwent a diagnostic laparoscopy using ICG technologies to assess the presence and severity of ischemic and necrotic intestinal changes. After six months from the date of discharge, the patient continues to be followed-up by a cardiologist.Conclusions. The timely performance of spiral computed tomography in patients with suspected acute mesenteric ischemia in the vascular regimen, angiography, endovascular interventions to restore blood supply to the intestine and ICG control of perfusion is appropriate to improve the treatment outcomes of this category of patients.

In the pattern of abdominal complications after cardiac surgery, acute mesenteric ischemia is rare but high-mortality pathology. In the initial stages, the disease has no specific signs, which makes it difficult to perform early multislice computed tomography to diagnose it. Risk stratification and an individual approach to the choice of diagnostic and therapeutic measures aimed at early restoration of mesenteric blood flow will reduce the mortality in this complication.
