Primary aortoenteric fistula is a very rare consequence of the evolution of an abdominal aortic aneurysm (AAA). The 3rd and 4th portion of the duodenum are involved in up to 80% of all cases. Frequently, gastrointestinal bleeding represents the first symptom, and diagnosis is difficult because of the aspecific clinical presentation and course, characterized by alternating remission and relapse; this is the reason why surgical treatment is usually delayed and therefore such events are managed as emergencies with a preoperative and intraoperative high death rate. We report the case of a 76-year-old man with a primary aortoduodenal fistula, who was submitted to gastric resection according to Billroth II 20 years before. This case could be interesting for its anatomical peculiarities favourable to the formation of the fistula.

Abstract
Primary aortoenteric fistula is a very rare consequence of the evolution of an abdominal aortic aneurysm (AAA). The 3rd and 4th portion of the duodenum are involved in up to 80% of all cases. Frequently, gastrointestinal bleeding represents the first symptom, and diagnosis is difficult because of the aspecific clinical presentation and course, characterized by alternating remission and relapse; this is the reason why surgical treatment is usually delayed and therefore such events are managed as emergencies with a preoperative and intraoperative high death rate. We report the case of a 76-year-old man with a primary aortoduodenal fistula, who was submitted to gastric resection according to Billroth II 20 years before. This case could be interesting for its anatomical peculiarities favourable to the formation of the fistula.Pubblicazioni consigliate
