The article describes a clinical case of recanalization of the superior mesenteric artery during acute mesenteric ischemia in an 81-year-old patient who was admitted to the emergency hospital in Ryazan with a clinic for “acute” abdomen. As a result of a diagnostic study, collection of anamnestic data and clinical picture, a diagnosis was made: “Embolism of mesenteric vessels.” Taking into account the early diagnosis (less than 4 hours from the onset of the disease), as well as the extremely complicated somatic status, selective angiography with mesentericography was performed, which revealed the patency of the main trunk of the superior mesenteric artery and complete occlusion of the distal segment of the intestine. Revascularization was performed ischemic area of the superior mesenteric artery. In the postoperative period, positive dynamics was observed, with complete relief of the clinical manifestations of mesenteric ischemia. On the 12th day, the patient was discharged for outpatient treatment under the supervision of a surgeon at her place of residence in satisfactory condition.

Artificial Intelligence (AI) is a rapidly developing field of research that attracts significant funding from both the state and industry players. Such interest is driven by a wide range of AI technology applications in many fields. Since many AI research topics relate to computer science, where a significant share of research results are published in conference proceedings, the same applies to AI. The world leaders in artificial intelligence research are China and the United States. The authors conducted a comparative analysis of the bibliometric indicators of AI conference papers from these two countries based on Scopus data. The analysis aimed to identify conferences that receive above-average citation rates and suggest publication strategies for authors from these countries to participate in conferences that are likely to provide better dissemination of their research results. The results showed that, although Chinese researchers publish more AI papers than those from the United States, US conference papers are cited more frequently. The authors also conducted a correlation analysis of the MNCS index, which revealed no high correlation between MNCS USA vs. MNCS China, MNCS China/MNCS USA vs. MSAR, and MNCS China/MNCS USA vs. CORE ranking indicators., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)
