Off-Label Iliac Side Branch Application For Salvage Of An Accessory Renal Artery

Purpose: To present the off-label use of an iliac side branch device to connect an accessory right renal artery to a bifurcated endograft in infrarenal aortic aneurysm repair. Case Report: An 83-year-old woman with a 54-mm infrarenal abdominal aortic aneurysm underwent endovascular repair using an iliac side branch device for accessory renal artery salvage. The procedure was technically successful, and no immediate perioperative adverse events were encountered. The creatinine level increased slightly. Six-month follow-up imaging revealed no endoleaks or occlusion. Conclusion: Considering the higher perioperative risk associated with open or hybrid procedures for similar cases, this off-label application of a well-recognized endovascular device deserves consideration as an alternative treatment option.
