[Rupture of an aneurysm of the splenic artery into the pancreas, a rare cause of gastrointestinal bleeding (author's transl)].
In a 73 year old man, repeated gastrointestinal haemorrhages first attributed to peptic oesophagitis, recurred despite anti-reflux surgery. Upper endoscopy being negative, arteriography was performed which revealed the presence of a fissured aneurysm of the splenic artery. This was successfully treated by left splenopancreatectomy. A communication between the aneurysm and wirsung's duct was found in the operative specimen. This a very rare cause of gastrointestinal bleeding. The diagnosis can be made only by arteriography.
