Crossed fused renal ectopia, a congenital anomaly in 1 of 7,000 individuals, presents a challenge during endovascular treatment of abdominal aortic aneurysm. Most treatment approaches in these patients have involved open surgical repair of the aneurysm or endovascular repair with coverage of the ectopic renal artery. We present what we think is the first case of endovascular abdominal aortic aneurysm repair with use of the chimney technique (parallel stent-grafting) to preserve an ectopic renal artery, in an 88-year-old man who was at high risk for open surgery. In addition to the patient's case, we discuss the relevant medical literature.
交叉融合型肾异位是一种先天性异常，发生率为七千分之一，在腹主动脉瘤的血管内治疗过程中是一个挑战。这些患者的大多数治疗方法包括对动脉瘤进行开放手术修复或对异位肾动脉进行覆膜的血管内修复。我们报告了我们认为的首例采用烟囱技术（平行支架植入）保留异位肾动脉的腹主动脉瘤血管内修复病例，患者为一名88岁的男性，其接受开放手术的风险很高。除了该患者的病例外，我们还讨论了相关医学文献。
