Acute thrombotic occlusion of a brachiocephalic branch graft and pseudoaneurysm formation after debranching surgery for a “non‐A non‐B” aortic dissection

Non‐A non‐B aortic dissection is a pathology with potentially life‐threateningconsequences, and aortic debranching followed by thoracic endovascular aorticrepair is one of the possible treatment options. Branch graft occlusion is aninfrequent complication and no definite guidelines exist about postoperativeantithrombotic therapy nor preoperative evaluation of individual anatomicalcharacteristics—in particular regarding cerebral circulation—in such patients. Wepresent the case of a 54‐year‐old man undergoing an aortic debranching procedurefor a thoracoabdominal aortic dissection originating in the aortic arch, complicatedby thrombotic occlusion of the brachiocephalic branch of the prosthesis andpseudoaneurysm of the ascending aorta, with our management and considerations.
