| Popis: | Highlights • Aortoduodenal fistula is a rare cause of gastrointestinal bleeding. However, it is life threatening. • Diagnosis requires a high level of clinical suspicion, and surgery can offer the best chance of survival. • Primary aortoduodenal fistula is often caused by aortic aneurysm without any previous vascular intervention. • Secondary aortoduodenal fistula occurs after surgical treatment for abdominal aortic aneurysm. Introduction Aortoduodenal fistula (ADF) is a rare but life-threating condition, and it is an important cause of massive gastrointestinal bleeding. Primary ADF often occurs as a result of aortic aneurysm, and secondary ADF develops after the placement of aortic prosthetic graft. Presentation of cases Case 1: A 64-year-old man with hematemesis was transferred to our hospital. The patient was diagnosed with primary ADF. Thus, we performed prosthetic graft replacement for an aortic aneurysm, and suturing of the duodenal fistula and duodenojejunal side-to-side anastomosis were performed. He was then discharged on the 35th postoperative day. After 2 years and 10 months, he died of other diseases. Case 2: A 76-year-old man with a history of abdominal aortic aneurysm repair with a prosthetic graft 5 years back who presented with hematemesis and melena was transferred to our hospital. The patient was diagnosed with secondary ADF, and an emergency endovascular aneurysm repair (EVAR) and suturing of the duodenal fistula were perfomed. He was transferred for rehabilitation purposes on the 108th postoperative day but eventually died of pneumonia 6 months after surgery. Discussion ADF is associated with high mortality. Initial bleeding is usually minor and often intermittent. However, it leads to severe bleeding and hemorrhagic shock. EVAR is preferred over open surgery because it can be performed faster and is less invasive. Recently, in case of hemorrhagic shock, EVAR is used as first-line treatment. Conclusion Accurate diagnosis and immediate treatment are important for the survival of patients with ADF. |
