Intestinal bleeding from abdominal aortic aneurysm is a rare complication; it represents an exceptional occurrence in patients with abdominal aortic prosthesis. The Authors report one case of intestinal hemorrhage caused by interruption in the posterior suture-line between prosthesis and aorta. The hemorrhage has been the cause of death in this patient 4 months after the operation; the exact diagnosis has been recognized only at autopsy, after a gastroduodenal resection performed for a suspected bleeding peptic ulcer. Pathology, ethiology and diagnosis of this case are commented and discussed.

One hundred and twelve cases of primary aortoduodenal fistulas were reviewed. The most common etiological agent was an atherosclerotic infrarenal abdominal aortic aneurysm. There was a male to female predominance of 9:2 with an average age of 62 years. Most fistulas occurred between an infrarenal aneurysm and the third portion of the duodenum because of the relatively fixed position of the duodenum and its direct anatomical relationship posteriorly with the aorta. Patient symptoms may vary from abdominal or back pain with gastro-intestinal bleeding to just hematemesis or melena. Twenty per cent gave a history of abdominal aneurysm while up to 70% may have an abdominal mass on physical examination at the time of admission. Tentative diagnosis is established by history and physical examination with duodenoscopy, barium duodenogram and angiography available only if temporally feasible. Surgical exploration is the only treatment with resection of the aneurysm, synthetic graft placement and duodenal suturing as the procedure of choice.

Intermittent intestinal bleeding persisted in a 77-year-old male, who had undergone grafting for abdominal aortic aneurysm. Each attack lasted for a few weeks and spontaneously resolved. Only a minute abnormality was found in the third portion of the duodenum; barium studies showed a segmental narrowing, but endoscopy disclosed only a small erosion in that portion. Massive and fatal gastrointestinal hemorrhage broke out 6 months after the onset of bleeding. Autopsy revealed an adhesion area with a small fistula formation between the duodenum and aorta. Even slight endoscopic findings should be considered suggestive of aortoenteric fistula in patients after aortic surgery.

Aorto-enteric fistula (AEF) is a very rare entity. Any direct or indirect communication between the arterial tree and the intestine represents a life threatening situation. Major symptom is gastro-intestinal bleeding with varying longevity and gravity. Preoperative diagnosis is difficult and this is why higher level of suspicion is necessary. Presence of Abdominal Aortic Aneurysm (AAA) or aorto-iliac grafts makes the diagnosis more likely. AEF are: primary, predominantly a complication of ruptured AAA, and secondary, after aorto-iliac reconstruction. The most frequent location of AEF is the end part of tue duodenum. In the group of secundary AEF the paraprosthetic type represents the most frequent morphological findings. Preoperative confirmation of an AEF however proved difficult despite the improvement in endoscopic and imaging technology. Diagnostic modality of choice is enhanced computed tomography. Management is surgical only. The choice of surgical repair is still controversial. Every effort must be made to prevent its occurrence by separating bowel and artery at the first aortic operation. Our experience in diagnosis and treatment of AEF is based on 3 cases with aorto-duodenal fistulas. Pathogenesis, clinical features and therapeutic aspects are presented and discussed.

Immunoglobulin G4- (IgG4-) related inflammatory abdominal aortic aneurysm (AAA) has been recognized as a manifestation of IgG4-related disease (IgG4-RD). We experienced one patient with multiple consecutive manifestations before and after endovascular stent grafting for IgG4-related inflammatory AAA (IAAA). A 71-year-old man was diagnosed with IgG4-RD due to increased IgG4 serum concentration, typical findings of parotid gland biopsy, and periaortitis in another hospital 2 years and 7 months before visiting our hospital. He came to our hospital because of abdominal pain and IAAA. He developed paraplegia after hospitalization and underwent endovascular stent grafting for the IAAA. About one month after stent grafting, he developed perforation of the sigmoid colon due to enteritis. He also had myocardial infarction. Finally, he died of intestinal bleeding. Here, we describe this case with rare, multiple, consecutive manifestations of IgG4-RD, some of which might be caused by IgG4-related IAAA or side effects of treatments rather than by IgG4-RD itself. We report this case because the clinical course seemed rare for IgG4-RD or IgG4-related IAAA. For treating IgG4-RD with IgG4-related IAAA, we should consider factors causing the symptoms and carefully select the proper treatment.
