Endovascular repair continues to pose a formidable technical challenge in the cases of aneurysm, dissection, and proximal type I endoleak involving the aortic arch. During the process of covering the aortic arch by stent graft to achieve better sealing, maintaining blood flow to the vital supra-aortic branches is difficult. We present a case of successful endovascular treatment of secondary type I endoleak by a double-chimney technique in a 36-year-old woman who had previously undergone a complicated descending aortic dissection repair. This endovascular technology might offer a new option to simultaneously preserve the innominate artery and the left carotid artery for total reconstruction of the aortic arch. © 2011 Society for Vascular Surgery.
