Pneumatosis portomesenteric is an unusual radiological finding that traditionally has been associated with mesenteric acute ischemia, although there are many causes that may produce. It is associated with penumatosis intestinalis in 82% of cases, indicating severe abdominal pathology. Clinical diagnosis is difficult and the radiological study of choice is CT scan. The treatment depends on the underlying condition. Emergency laparotomy is indicated when data of mesenteric ischemia without massive intestinal necrosis, in- testinal obstruction with signs of strangulation, abdominal trauma with vascular injury or complicated inflammatory disease are present. Prognostic is poor in those cases associated with mesenteric ischemia, improving very much when the cause is not ischemic.
门静脉肠系膜积气是一种不常见的影像学表现，传统上与肠系膜急性缺血相关，尽管有多种原因可导致其出现。82%的病例与肠积气相关，提示存在严重的腹部病变。临床诊断困难，首选的影像学检查是CT扫描。治疗取决于潜在病因。当出现肠系膜缺血但无大面积肠坏死、绞窄性肠梗阻体征、伴有血管损伤的腹部创伤或复杂的炎症性疾病等情况时，需行急诊剖腹手术。与肠系膜缺血相关的病例预后较差，若病因非缺血性，则预后会显著改善。
