急性肠系膜缺血是外科急症,死亡率高达40％～100％,临床体征和实验室检查均缺乏特异性表现。闭塞或非闭塞性肠系膜动脉缺血、静脉血栓、血管炎或夹层动脉瘤均可导致肠系膜缺血。病理改变包括轻微粘膜水肿至迅速全小肠坏死,以往大多数研究表明平片一般无特异性征象。该组男性11例,女性15例,年龄22～91岁,平均63.8岁。21例有素因性疾病。病人经血管造影(12例)、手术病理(13例)和尸检(1例)证实为肠系膜缺血。本组病例不包括肠绞窄、肿瘤或外伤引起的血管病变。CT扫
Acute mesenteric ischemia is a surgical emergency with a mortality rate of 40% to 100%. Clinical signs and laboratory tests lack specific performance. Mesenteric ischemia, occlusive or non-occlusive mesenteric artery ischemia, venous thrombosis, vasculitis, or dissecting aneurysms can all lead to mesenteric ischemia. Pathological changes, including mild mucosal edema to rapid total intestinal necrosis, the vast majority of studies have shown that plain film generally no specific signs. The group of 11 males and 15 females, aged 22 to 91 years, an average of 63.8 years old. 21 cases of natural causes of disease. Patients underwent angiography (12 cases), surgical pathology (13 cases) and autopsy (1 case) confirmed mesenteric ischemia. This group of patients does not include intestinal strangulation, tumor or trauma caused by vascular disease. CT scan
