Abstract

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.
移植肾切除术后血管内支架移植治疗假性动脉瘤
介绍。移植肾切除术后的血管并发症相当罕见。本文的目的是分析支架植入治疗移植肾切除术后假性动脉瘤的有效性。临床病例。在过去的23年里,一位50岁的患者接受了3次来自尸体供体的肾脏移植和2次移植肾切除术。在左肾移植切除术12年后,他抱怨腹痛,并在他的左盆腔区域脉动肿块入院。电脑断层血管造影、超音波及动脉造影均显示一巨大假性动脉瘤源自左髂外动脉。支架植入术解决了这个问题,提供了成功的临床和影像学结果。结论。该病例的治疗选择是开放或血管内技术。手术翻修与并发症的高风险相关。血管内治疗具有微创和低失血量的优点。
