Primary aorto-enteric fistulae are rare. Preoperative diagnosis is important but is difficult and cannot usually be confirmed by upper gastrointestinal series, aortography and endoscopy. Computed tomography demonstrating an abdominal aortic aneurysm with air bubbles in its wall and "soft tissue" mass posteriorly should raise the possibility of penetration of the aneurysm into the lumen of the bowel and related consequences (hematoma, sepsis, infected operating field).
原发性主动脉肠瘘很少见。术前诊断很重要，但难度较大，通常无法通过上消化道造影、主动脉造影和内镜检查来确诊。计算机断层扫描显示腹主动脉瘤壁内有气泡且后方有“软组织”肿块时，应考虑动脉瘤穿入肠腔及相关后果（血肿、脓毒症、术野感染）的可能性。
