Abstract:
Three cases are presented of a rare complication of abdominal aorta aneurysm, that is its rupture into the gastrointestinal tract. In two cases the aneurysm ruptured into the duodenum, and in one case into small intestine. The authors call attention to the variety of symptomatology and diagnostic difficulties with the primary aorto-intestinal fistula. This is true especially of cases in which the rupture is the first and not infrequently the only symptom of the aneurysm. The rupture of the abdominal aorta aneurysm into the gastrointestinal tract is still fraught with a very high mortality; out of three patients with primary aorto-intestinal fistula only one was saved.
