Case Report: We report an unusual case of a 65-year-old male patient with horseshoe kidney, who underwent a successful open repair for an abdominal aortic aneurysm (AAA). The accessory renal arteries were perfused with histidine-tryptophan-ketoglutarate (HTK) solution (Custodiol®; Dr. Franz-Kohler Chemie GmbH, Bensheim, Germany) during the vascular reconstruction. There were no creatinine and estimated glomerular filtration rate (eGFR) modifications in the postoperative time. In the literature, only two cases of Custodiol solution for kidney protection during aortic surgery are reported. To the best of our knowledge, this is the first case of Custodiol perfusion for horseshoe kidney protection. Discussion: The concomitant presence of horseshoe kidney and an AAA requires a specific preoperative planning. This is necessary to define the appropriate surgical procedure and strategy. The onset of acute kidney injury is an aspect that must always be taken into consideration during aortic surgery, even more in the case we are reporting. Indeed, despite the complexity of the kidney anatomy, the use of Custodiol solution allowed a proper maintenance of the perioperative renal function, as shown by the postoperative levels of creatinine and eGFR. Conclusions: Preoperative planning and organ preservation are crucial in AAA open repair, especially in the presence of congenital anomalies such as horseshoe kidney.
