Although rare, visceral artery aneurysms are reported with increasing frequency, mostly as a result of the growing use of angiography in unclear cases of abdominal symptoms. The splenic artery aneurysms are by far the most common, followed in frequency by the renal and hepatic artery aneurysms. The splenic and renal artery should undergo surgery in all cases of symptomatic aneurysms, asymptomatic aneurysms discovered in pregnant women or women of child-bearing age, aneurysms with documented growth, and aneurysms with a diameter more than 2 cm. The hepatic artery aneurysms as well as the more rare aneurysms should be treated surgically as soon as the diagnosis is established because the natural course of these aneurysms seems to be progression to rupture. In high risk patients, transcatheter arterial embolisation has recently proven to be a useful alternative to surgery in many cases.
尽管内脏动脉瘤较为罕见，但报告的病例越来越多，这主要是由于在腹部症状不明的情况下血管造影术的使用日益增加。脾动脉瘤是迄今为止最常见的，其次是肾动脉瘤和肝动脉瘤。对于所有有症状的动脉瘤、在孕妇或育龄妇女中发现的无症状动脉瘤、有记录显示生长的动脉瘤以及直径超过2 cm的动脉瘤，脾动脉和肾动脉动脉瘤均应接受手术治疗。一旦确诊，肝动脉瘤以及更罕见的动脉瘤应立即进行手术治疗，因为这些动脉瘤的自然病程似乎是发展至破裂。在高危患者中，最近经导管动脉栓塞术已被证明在许多情况下是一种有用的手术替代方法。
