Aneurysms of the superior mesenteric artery (SMA) and branches thereof are uncommon but have a high rate of rupture and mortality relative to other visceral artery aneurysms. Historically, the predominant etiology has been infectious; with a renewed rise in intravenous drug abuse rates in the last decade, we hypothesize a resurgence in septic embolic complications may occur in the coming years. Here, we describe the presentation and management of 2 cases of intravenous drug users presenting with infectious endocarditis and SMA main trunk and branch aneurysms, one of which was ruptured. In addition, we review the literature on these rare clinical entities.
肠系膜上动脉（SMA）及其分支的动脉瘤并不常见，但相对于其他内脏动脉瘤，其破裂率和死亡率较高。从历史上看，主要病因是感染性的；随着过去十年静脉药物滥用率的再次上升，我们推测未来几年脓毒性栓塞并发症可能会再次出现。在此，我们描述了2例静脉药物使用者出现感染性心内膜炎以及SMA主干和分支动脉瘤的临床表现及治疗情况，其中1例发生了破裂。此外，我们还回顾了关于这些罕见临床实体的文献。
