Primary aortoenteric fistula is a rare but fatal cause of gastrointestinal bleeding and requires urgent intervention. A high index of clinical suspicion in conjunction with imaging is required because a favorable outcome relies on prompt diagnosis. The primary forms of aortoduodenal fistulas are nearly always associated with abdominal aortic aneurysm, mostly atherosclerotic. Technological advances in imaging, particularly computed tomography (CT), play a pivotal role in the preoperative detection of these fistulas. We report the case of a 76-year-old man who was diagnosed with a large abdominal aortic aneurysm with associated contained rupture and suggestion of an aortoduodenal fistula on CT. This case demonstrated the effectiveness, ease, and low cost of the preoperative evaluation and documentation of a primary aortoduodenal fistula using CT scans.
原发性主动脉肠瘘是一种罕见但致命的胃肠道出血原因，需要紧急干预。由于良好的预后取决于快速诊断，因此需要高度的临床怀疑指数和影像学检查。原发性主动脉肠瘘几乎总是与腹主动脉瘤有关，主要是动脉粥样硬化。影像学，特别是计算机断层扫描（CT）的技术进步在这些瘘管的术前检测中起着关键作用。我们报告了一例 76 岁男性，其被诊断为大型腹主动脉瘤，伴有包裹性破裂，并在 CT 上提示存在主动脉肠瘘。该病例证明了使用 CT 扫描对原发性主动脉肠瘘进行术前评估和记录的有效性、简便性和低成本。
