Abstract

Objectives: To present initial experience with a new modular transfemoral multibranched stent graft for treating aortic arch aneurysms. Methods: Six patients, considered high risk for open surgery, were treated with custom made branched stent grafts. All patients had a staged left carotid subclavian bypass before the endovascular procedure. Each branched graft had a 12 mm side branch for the innominate artery and an 8 mm side branch for the left common carotid artery. Results: Four patients out of six had uneventful placement of the prostheses, with successful exclusion of their aneurysms. One patient developed a type I endoleak that was managed successfully with coiling and gluing of the aneurysm sac. In one patient, cannulation of the innominate branch was unsuccessful and an extra-anatomic bypass was necessary to perfuse the right carotid and vertebral arteries. This patient developed a stroke, while one more suffered a right cerebellar infarct. Conclusion: We have demonstrated the technical feasibility of a modular transfemoral branched stent graft for treatment of aortic arch aneurysms. The method is relatively safe based on initial experience. More cases and long-term follow up are necessary to evaluate the efficacy and safety of this new device. © 2012 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.
