Ectopic major renal arteries are rare but anatomically important because they can complicate aortic surgery and make the operation challenging for vascular surgeons. A 68-year-old male was presented with a 5.5-cm aneurysm of the infrarenal abdominal aorta combined with an ectopic main right renal artery arising from the middle of the aneurysm sac, perfusing a normotopic right kidney. The patient also had small right common iliac artery aneurysm. Open repair was performed with reimplantation of the right renal artery on the aortic tube graft, the right kidney was perfused with cold heparinized lactated Ringer solution during operation. The right common iliac artery aneurysm was wrapped with a polyester band. The patient's postoperative courses were uneventful, with normal renal function during 5 years of follow-up. Preoperative planning is important for achieving optimal results in treating complex aneurysms with ectopic main renal artery.
异位主要肾动脉很少见，但在解剖学上很重要，因为它们会使主动脉手术变得复杂，并给血管外科医生的手术带来挑战。一名68岁男性患者，肾下腹主动脉有一个5.5厘米的动脉瘤，同时有一条异位的右主肾动脉从动脉瘤囊中部发出，为正常位置的右肾供血。患者还患有右侧髂总动脉瘤。通过将右肾动脉重新植入主动脉人工血管进行开放修复，术中用冷肝素化乳酸林格液灌注右肾。右侧髂总动脉瘤用聚酯带包裹。患者术后恢复顺利，随访5年肾功能正常。术前规划对于治疗伴有异位主肾动脉的复杂动脉瘤以取得最佳效果很重要。
