目的：总结分析国内急性肠系膜缺血病例的临床特点，以提高对本病的认识。方法：检索2005～2009年中国期刊全文数据库有关急性肠系膜缺血的有效文献，记录相关数据并进行总结分析。结果：男性占65．6％，女性占34．4％。临床表现以突发腹痛最常见（92．6％）。临床分型有肠系膜动脉栓塞（33．0％）、肠系膜动脉血栓（5．0％）、非闭塞性肠系膜缺血（2．0％）、肠系膜静脉血栓（61．0％）。心房颤动、肝硬化、腹部手术史、高血压为急性肠系膜缺血常见高危因素。腹部 B 超、腹部 CT/CTA 在急性肠系膜缺血诊断的敏感性分别为46．2％、76．5％。结论：国内文献报道的急性肠系膜缺血男性多于女性，临床分型中以肠系膜静脉血栓为主。腹部CT/CTA可作为急性肠系膜缺血的重要诊断方法。“,” Objective: To investigate the clinical profiles of acute mesenteric ischemia so as to improve the understanding of the disease. Methods: Cases-analyze literatures on acute mesenteric ischemia from 2005 to 2009 in Chinese Periodical Full-text Database were retrieved and the data needed were recorded and analyzed. Results:Among the recorded information, male accounted for 65.6% and female accounted for 34.4%. Sudden abdominal pain was the most common clinical manifestation. The proportion of arterial embolism, arterial thrombosis, nonocclusive mesenteric ischemia and venous thrombosis was 33.0%,5.0%,2.0% and 61.0% respectively. Atrial fibrillation, cirrhosis, abdominal surgery, hypertension are the mainly risk factors of acute mesenteric ischemia. The sensitivities of abdominal ultrasound and abdominal CT/CTA in the diagnosis of acute mesenteric ischemic were 46.2% and 76.5%. Conclusion: It is reported in China that acute mesenteric ischemia occured more frequent in male. Most patients were venous thrombosis type. Abdominal CT/CTA can be used as the principal diagnosis of acute mesenteric ischemia.
