STUDY AIM: Gastrointestinal bleeding by rupture of splanchnic artery aneurysms is very rare. The aim of this study is to report four cases observed between 1990 and 1996. MATERIALS AND METHODS: In the first case, the celiac trunk aneurysm was revealed by hematemesis due to erosion of the posterior wall of the stomach. Excision of the aneurysm associated with splenopancreatectomy was followed by revascularization of the common hepatic artery with a bypass implanted in the aorta. The second case concerned a splenic artery aneurysm revealed by hemosuccus pancreaticus and intestinal bleeding which was treated by excision and splenopancreatectomy. In the third case, the common hepatic artery aneurysm revealed by hemosuccus pancreaticus and intestinal bleeding was treated by obstructive endoaneurysmorrhaphy. The fourth case concerned a superior mesenteric aneurysm revealed by duodenal erosion causing gastric and intestinal bleeding, which was treated by obstructive endoaneurysmorrhaphy and revascularization of the mesenteric artery by a spleno-mesenteric bypass. RESULTS: Surgical treatment was successful in all four patients. In the first case, an acute acalculous cholecystitis required a cholecystectomy after 3 weeks. In the fourth case, a splenic infarction disappeared spontaneously. CONCLUSION: Such observations are rare. The site of the bleeding was located by endoscopy. The aneurysm was recognized by contrast-enhanced computerized tomography (CT) scan and/or celiac and mesenteric arteriography which was performed in all cases and was very useful for the management of such aneurysms. After excision (n = 2) or obliterative endoaneurysmorrhaphy (n = 2), revascularization had to be done in two cases for celiac and mesenteric aneurysms.
