After patient-informed consent and local Ethical Committee and Italian Public Health Ministry authorization, three multilayer stents were implanted in the thoracoabdominal aortic tract, obtaining at a 20-month computed tomography scan follow up, a complete exclusion of the TAAA, with normal patency of visceral vessels.Conclusion: Multilayer stents can be used in thoracoabdominal aortic aneurysm, with positive results.Keywords: chimney technique, renal artery stenosis, thoracoabdominal aneurysm, vascular complication
