Endovascular grafting via the aortic arch, a novel alternative method for aortic aneurysm repair, was performed in 18 patients with aortic arch or distal arch aneurysms. For cerebral protection, selective or retrograde cerebral perfusion was used during delivery and deployment of the stented graft through the aortotomy. Selective cerebral perfusion was performed through both cerebral arteries and the left subclavian artery. Throughout this procedure, the aorta was filled with carbon dioxide to prevent the spinal arteries from air embolism. Two patients were lost, one due to myocardial infarction and one due to pneumonia. Endoluminal leakage was found in 2 patients, for which reoperation was required. However, no cerebral or spinal complications were observed in this series. Thus we conclude that endovascular stent grafting via the aortic arch is an acceptable alternative for the aortic arch or distal arch aneurysm repair with little risk of cerebral or spinal complications.
