Endovascular treatment of the pseudoaneurysm using stent-graft after transplant nephrectomy

Introduction. Vascular complications after transplant nephrectomy are rather rare. The aim of this article is to analyze the effectiveness of the stent-graft implantation in the treatment of pseudoaneurysm after transplant nephrectomy. Clinical case. In the previous 23 years, a 50-year-old patient underwent 3 kidney transplantations from a cadaveric donor and 2 transplant nephrectomies. At 12 years after the left transplant nephrectomy he complained of abdominal pain and was admitted for a pulsating mass in his left pelvic region. Computed tomography angiography, ultrasonography, and arteriography were performed and showed a large pseudoaneurysm arising from the left external iliac artery. The stentgraft implantation solved the problem providing successful clinical and radiological results. Conclusion. Treatment options in this case were open or endovascular techniques. Surgical revision associated with high risk of complications. Endovascular treatment had the benefits of a minimally invasive approach with low blood loss.
