Description
Summary:Department of Cardiovascular Surgery, University Medical Center Freiburg, Hugstetter Str. 55, 79106 Freiburg, Germany *Corresponding author. Tel.: +49 (0)761 270 8888; fax: +49 (0)761 270 2788. E-mail address : mail{at}dr-luehr.net (M. Luehr). We describe the case of an 11-year-old girl with an abdominal neuroblastoma which was operated and intraoperatively irradiated nine years ago. After six years, she developed stenoses of the infrarenal abdominal aorta and both renal arteries. Initial treatment of the stenosed vessels comprised endovascular balloon dilatations and repeated stent-graft implantations, including drug eluting stents. However, severe in-stent stenoses occurred during follow-up and the girl developed acute renal failure. Open surgery was performed with two extra-anatomic bypasses, a thoracic-to-abdominal aortic bypass and a left iliac-to-renal bypass, on an urgent basis. The postoperative course was uneventful and the patient was discharged home two weeks after the operation with full recovery of renal function. We conclude that endovascular stent-graft placement in children can only be a palliative treatment due to outgrowing of the stent-graft and the potential risk of re-stenosis, especially after a history of irradiation. Vascular surgery with placement of extra-anatomic bypasses will provide a definite treatment. Key Words: Aorta/aortic; Renal; Stenosis; Radiation therapy; Neuroendocrine tumor
