AbstractSide-clamping of the ascending aorta is an indispensable technique for proximal anastomosis in total debranching of supra-aortic trunks and in endovascular aneurysm repair for arch aneurysm. However, this procedure may lead to the dislodging of multiple plaques and to clamp injury of the ascending aorta. We developed a clampless technique to achieve proximal anastomosis between the ascending aorta and an artificial graft used for total debranching of supra-aortic trunks. We applied this method in six patients with arch aneurysm and a plaque-rich ascending aorta and were able to achieve total debranching of the supra-aortic trunks in all of the patients without side-clamping the ascending aorta and no procedurally related complications. This clampless anastomosis technique ("real chimney technique") in the ascending aorta is a valuable option for total debranching of supra-aortic trunks in the hybrid repair of arch aneurysms.
