Branch thoracic stent graft repair for arch aneurysm.

Aortic arch aneurysms involving the major vessels of the neck pose great challenges in their repair. Open repair of these aneurysms are associated with a significant morbidity and mortality. The major challenge for endovascular repair of these complex aneurysms is the maintenance of cerebral perfusion during stent implantation and long-term durability. This paper discusses preoperative planning and technical aspects to successful endovascular repair of a large aortic arch aneurysm involving the distal take-off of the left subclavian artery.
