Anatomical Feasibility of the "Canaud Technique" for Physician-Modified Thoracic Endovascular Grafts for the Treatment of Aortic Arch Disease.

Thoracic endovascular aortic repair (TEVAR) has been extended to more proximal landing zones for the treatment of aortic arch aneurysm, dissections, penetrating aortic ulcers. Among total endovascular solutions, the "Canaud technique" for Physician-Modified Thoracic Endovascular Grafts (C-PMEGs) has gained acceptance with good early results. The anatomical feasibility in 164 consecutive patients was 69 patients (42.1%), with the combination of supra-aortic trunks (SAT) bypass or the use of covered stent in IA or left common carotid artery (LCCA) as adjunctive maneuvers, showing that the C-PMEG technique is a viable option in aortic arch lesions endovascular treatment.
