Primary aortoenteric fistulae (AEFs) are rare vascular entities. More than 75% of primary AEFs involve the duodenum, with the overwhelming majority located in the third or fourth portion. @entity731 , leading to formation of an @entity449 , remains the most common etiology, accounting for more than 3/4 of the cases reported. Primary aortoenteric fistulae following radiotherapy are rare. The case of a 49-year-old @entity1 with @entity292 22 years after para-aortic radiation is presented. In November 1997, the @entity1 suddenly developed @entity6552 and @entity476 . Endoscopy suggested the presence of an ulcus but no definitive @entity548 source could be seen. Bleeding stopped spontaneously. Six hours later he developed massive @entity6552 and was transferred to our department. An emergency operation was performed. We found an @entity2009 in the third portion of the duodenum without an @entity449 . We directly sutured the aortic wall laceration and resected the third and fourth part of the duodenum. Histology revealed typical signs of radiation damage. The @entity1 is alive and well 2 years after surgery. To our knowledge, this is the sixth case of a primary @entity2009 following radiotherapy ever to be reported in world literature.
