The laboratory assessments yielded high creatinine levels, indicating an acute renal impairment. Computed tomography angiography revealed an aorto-caval fistula complicating infrarenal abdominal aortic aneurysm. The patient was successfully treated with the endovascular approach by deploying covered stent grafts that completely excluded the fistula.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Utilizing covered stent grafts for endovascular management of aorto-caval fistula is a good alternative to
