Non‐A non‐B aortic dissection is a pathology with potentially life‐threatening consequences, and aortic debranching followed by thoracic endovascular aortic repair is one of the possible treatment options. Branch graft occlusion is an infrequent complication and no definite guidelines exist about postoperative antithrombotic therapy nor preoperative evaluation of individual anatomical characteristics—in particular regarding cerebral circulation—in such patients. We present the case of a 54‐year‐old man undergoing an aortic debranching procedure for a thoracoabdominal aortic dissection originating in the aortic arch, complicated by thrombotic occlusion of the brachiocephalic branch of the prosthesis and pseudoaneurysm of the ascending aorta, with our management and considerations.
