Horseshoe kidney is the most common congenital renal anomaly, occurring in 0.15-0.25% of newborns. The association of a horseshoe kidney with an abdominal aortic aneurysm is rare. Only 0.12% of patients requiring abdominal aortic repair have a horseshoe kidney. This therapeutic challenge constitutes a patient presenting with a symptomatic abdominal aortic aneurysm and a horseshoe kidney. The horseshoe kidney was supplied by 4 renal arteries, 2 of which emerged from the aneurysmal sac. The patient underwent urgent open repair, with transperitoneal exposure, interposition of a bifurcated aorto-bi-iliac Dacron graft and re-implantation of the 2 anomalous renal arteries on the Dacron main body. Postoperatively, the patient was discharged from the intensive care unit on day 3, and discharged home on day 8, maintaining normal serum creatinine.
马蹄肾是最常见的先天性肾脏异常，在0.15%至0.25%的新生儿中出现。马蹄肾与腹主动脉瘤的关联罕见。仅0.12%需要进行腹主动脉修复的患者有马蹄肾。这种治疗挑战表现为一名出现症状性腹主动脉瘤且伴有马蹄肾的患者。马蹄肾由4支肾动脉供血，其中2支从动脉瘤囊发出。患者接受了紧急开放修复手术，经腹膜暴露，置入分叉的主动脉-双髂动脉涤纶移植物，并将2支异常肾动脉重新植入涤纶主体上。术后，患者于第3天从重症监护病房出院，第8天出院回家，血清肌酐维持正常。
