[Visceral aneurysms. Two case reports].

The authors report two case stories of visceral aneurysm: a 54 year-old man presenting recurrent gastrointestinal bleeding caused by a splenic artery aneurysm, and a 57 year-old man presenting with acute abdomen due to rupture of a hepatic artery aneurysm. Visceral aneurysms often present with classical gastrointestinal symptoms. They are connected with considerable mortality. Rupture requires instant surgery. In the elective phase the literature recommends embolization or resection.
