Retrograde ascending aortic dissection in the midterm period after thoracic endovascular aortic repair: a case report and literature review

Retrograde ascending aortic dissection (rAAD) is a catastrophic complication of thoracic endovascular aortic repair (TEVAR). A 56 year-old male patient who had undergone TEVAR for Stanford type B aortic dissection 6-month ago was admitted to our clinic with uncontrolled hypertension for the last twelve hours and history of a syncopal attack three days ago. Retrograde ascending aortic dissection was detected in computed tomography angiography. Ascending aorta and hemiarch replacement with a Dacron graft was safely performedviahypothermic circulatory arrest and antegrade cerebral perfusion for the treatment of rAAD after TEVAR.
