Long-term durability of aortic arch in situ stent graft fenestration requiring lifelong surveillance.

We report successful endovascular repair of a 61-year-old man treated for a 7.1-cm excentric aortic arch aneurysm by in situ stent graft fenestration for the brachiocephalic trunk and the left common carotid artery. Cerebral perfusion during the intervention was maintained by pump-driven extracorporal bypass to the right common carotid artery and to the left axillary artery provided with a left carotid-subclavian bypass. After 5 years of follow-up, the aortic arch in situ revascularization is still patent, the aneurysm excluded, and no endoleak detectable, although endovascular reintervention with distal aortic stent graft extension due to dilatation of the descending aorta was required.
