Accessory renal arteries are common and may contribute significantly to renal perfusion. With the current endovascular design and technology, it is possible to preserve accessory renal arteries during endovascular aneurysm repair (EVAR). We report two patients with custom-made EVAR devices to preserve accessory renal arteries with good mid- and long-term clinical and radiological results. Conventional EVAR would have occluded their origins. As a result of customized fenestrations in commercially available stentgrafts, the patency of large accessory renal arteries can be maintained, whilst securing a proximal seal.
副肾动脉很常见，对肾脏灌注可能有重要贡献。凭借当前的血管腔内设计和技术，在血管腔内动脉瘤修复术（EVAR）期间保留副肾动脉是可行的。我们报告了两名使用定制EVAR装置保留副肾动脉的患者，获得了良好的中长期临床和影像学结果。传统的EVAR会闭塞副肾动脉的起始部。通过在市售覆膜支架上定制开窗，可维持较大副肾动脉的通畅，同时确保近端密封。
