Introduction. Visceral artery aneurysms are uncommon. Among them, splenic artery is the most common (46-60%). Most splenic artery aneurysms are asymptomatic and diagnosed incidentally, but its rupture, potentially fatal, occurs in up to 8% of cases. Presentation of Case. A female patient, 64 years old, diagnosed with a giant aneurysm of the splenic artery (approximately 6.5 cm in diameter) was successfully submitted to endovascular treatment by stent graft implantation. Discussion. Symptomatic aneurysms and those larger than 2 cm represent some of the main indications for intervention. The treatment may be by laparotomy, laparoscopy, or endovascular techniques. Among the various endovascular methods discussed in this paper, there is stent graft implantation, a method still few reported in the literature. Conclusion. Although some authors still consider the endovascular approach as an exception to the treatment of SAA, in major specialized centers these techniques have been consolidated as the preferred choice, reserving the surgical approach in cases where this cannot be used. For being a less aggressive approach, it offers an opportunity of treatment to patients considered "high risk" for surgical treatment by laparotomy/laparoscopy.
引言。内脏动脉瘤并不常见。其中，脾动脉瘤最为常见（占46 - 60%）。大多数脾动脉瘤无症状，多为偶然发现，但高达8%的病例会发生破裂，这可能是致命的。病例介绍。一名64岁女性患者，被诊断为脾动脉巨大动脉瘤（直径约6.5厘米），通过支架植入术成功接受了血管内治疗。讨论。有症状的动脉瘤以及直径大于2厘米的动脉瘤是一些主要的干预指征。治疗方法可以是开腹手术、腹腔镜手术或血管内技术。在本文讨论的各种血管内方法中，有一种是支架植入术，该方法在文献中的报道仍然较少。结论。尽管一些作者仍将血管内治疗方法视为脾动脉瘤治疗的例外情况，但在主要的专业中心，这些技术已成为首选，仅在无法采用该方法的情况下才保留手术治疗。由于血管内治疗方法侵袭性较小，它为那些被认为开腹/腹腔镜手术治疗“高风险”的患者提供了治疗机会。
