True visceral artery aneurysms are potentially complex to treat but with advances in technology and increasing interventional radiology expertise over the past decade are now increasingly the domain of the interventional radiologist. BODY: The interventional approach is based on localization of the aneurysm and identification of the anatomical determinants to treat these lesions to prevent aneurysm rupture. Several different endovascular techniques are available and should be selected carefully, dependent on the aneurysm morphology. Standard endovascular treatment options include stent-graft placement and trans-arterial embolisation. Different strategies are divided into parent artery preservation and parent artery sacrifice techniques. Endovascular device innovations now include multilayer flow-diverting stents, double-layer micromesh stents, double-lumen balloons and microvascular plugs and are also associated with high rates of technical success.
Complex techniques such as stent-assisted coiling and balloon-remodeling techniques are useful techniques and require advanced embolisation skills and are further described.
真性内脏动脉瘤的治疗可能较为复杂，但随着过去十年技术的进步以及介入放射学专业知识的不断增加，现在越来越多地成为介入放射科医生的领域。
介入治疗方法基于动脉瘤的定位以及识别用于治疗这些病变以预防动脉瘤破裂的解剖学决定因素。有几种不同的血管内技术可供选择，应根据动脉瘤的形态仔细选择。标准的血管内治疗选择包括覆膜支架置入和经动脉栓塞。不同的策略分为保留母动脉和牺牲母动脉技术。血管内装置的创新现在包括多层血流导向支架、双层微网支架、双腔球囊和微血管栓塞栓子，并且技术成功率也很高。
诸如支架辅助弹簧圈栓塞和球囊重塑技术等复杂技术是有用的技术，需要先进的栓塞技能，并将进一步描述。
