[Intestinal complications from vascular prostheses]

Secondary FAE is a rare complication, usually located at the duodenum. The typical clinical presentation is like a digestive hemorrhage or a sepsis. We report two cases of FAE with atypical manifestations. The first case presented a lower digestive hemorrhage produced by the fistulization to the sigma. The second case appeared like an intestinal obliteration caused by the full emigration of a prosthesis to the jejunum. We wish to remark the importance of the clinical suspicion of a FAE (Key of diagnosis), and the sparing relevance of the complementary examinations and the urgency of a surgical treatment in order to avoid the high rate of morbi-mortality associated with this complication.
