Total Arch Repair Using Supra-Aortic Debranching Technique With Banding of the Ascending Aorta for Endovascular Stent Graft Fixation

Endovascular stenting requires a satisfactory landing zone that guarantees fixation and sealing of the proximal part of the endograft. We report total arch repair using supra-aortic debranching technique with banding of the ascending aorta for endovascular graft fixation. An 85-year-old man presented with hoarseness of voice. A fusiform aneurysm with a maximum transverse diameter of 62 mm on the aortic arch was identified by computed tomographic angiography. Supra-aortic arch debranching of the 3 neck vessels using a trifurcated graft and coronary arterial bypass grafting were performed while closely monitoring the regional cerebral oxygen saturation. The ascending aorta was dilated to 41 mm; we successfully reduced this to a mean outer diameter of 36 mm by banding the aorta using an expanded polytetrafluoroethylene surgical membrane. The endovascular procedure was performed 17 days after surgical intervention. The patient was extubated immediately after endovascular stent placement and spent 1 day in intensive care with no signs of transient or permanent neurologic events. A postoperative computed tomographic scan did not reveal any evidence of endoleak. The banding of the ascending aorta for endovascular graft fixation could facilitate endovascular aortic arch repair and provide an alternative treatment for high-risk patients.
