Superior mesenteric artery aneurysms are rare, accounting for less than 0.5% of all intra-abdominal aneurysms. They are mainly caused by atherosclerosis and septic emboli resulting from bacterial endocarditis. Although uncommon, these aneurysms are considered dangerous because of possible complications such as rupture with hemorrhage and intestinal ischemia. Since the consequences can be very serious, early diagnosis and treatment are essential to improve outcomes. Although there is no well-defined consensus, recommended treatments include open surgery, endovascular therapy, and watchful waiting with periodic examinations. In this article we report the case of an asymptomatic 58-year-old man with an incidental and unusual finding of two superior mesenteric artery aneurysms. Since anatomy was not favorable for an endovascular approach, open surgery was performed, using a dacron graft to successfully repair the artery.
肠系膜上动脉动脉瘤较为罕见，占所有腹内动脉瘤的比例不到0.5%。它们主要由动脉粥样硬化和细菌性心内膜炎引起的感染性栓子所致。尽管不常见，但这些动脉瘤因其可能出现破裂出血和肠缺血等并发症而被认为具有危险性。由于后果可能非常严重，早期诊断和治疗对于改善预后至关重要。虽然没有明确的共识，但推荐的治疗方法包括开放手术、血管内治疗以及定期检查下的密切观察等待。在本文中，我们报告了一例58岁无症状男性的病例，其偶然发现了两个不寻常的肠系膜上动脉动脉瘤。由于解剖结构不利于血管内治疗，遂进行了开放手术，使用涤纶移植物成功修复了动脉。
