Abstract

True aneurysm of the splenic artery is the third most common intraabdominal aneurysm and constitutes 60% of all visceral aneurysms. The incidence of splenic artery aneurysms ranges from 0.01% to as high as 10.4% in the elderly. In approximately 30% of cases, the aneurysm may rupture into a viscus. Aneurysmal rupture into the colon is a potentially fatal but extremely uncommon complication. We report a case of splenic artery aneurysm communicating with the descending colon, presenting as massive lower gastrointestinal tract bleeding. The patient was treated and survived the episode. In English literature, fewer than 15 cases have been described with only two patients surviving.

摘要

脾动脉真性动脉瘤是腹腔内第三常见的动脉瘤，占所有内脏动脉瘤的60%。脾动脉动脉瘤的发病率在老年人中从0.01%到高达10.4%不等。在大约30%的病例中，动脉瘤可能破裂进入脏器。动脉瘤破裂进入结肠是一种潜在致命但极其罕见的并发症。我们报告一例脾动脉动脉瘤与降结肠相通，表现为大量下消化道出血的病例。该患者接受了治疗并在此次发作中存活下来。在英文文献中，描述的病例少于15例，仅有两名患者存活。
