Retrograde type A aortic dissection (RTAD) is a severe complication of thoracic endovascular aortic repair (TEVAR). In this regard, we present our unique surgical methods for total arch and descending aorta replacement for RTAD after TEVAR for complicated type B aortic dissection (TBAD). A 52-year-old man with a history of distal arch large aneurysm was diagnosed with TBAD. Because he had sustained chest pain and his aneurysm diameter was 67 mm, TEVAR was urgently performed. After a right axillary-left axillary artery bypass, a stent graft was deployed in the descending aorta via the right femoral artery. Coil embolization was performed in the left subclavian artery. After the condition of the stent graft was checked by angiography, no Type 1 endoleak and backflow from the re-entry was observed. However, seven days after the operation, he experienced chest pain suddenly.  Computed tomography (CT) revealed forward blood flow in the descending aorta (type IA endoleak) and thrombosed aortic dissection in the ascending aorta. The distal arch diameter exceeded 70 mm. A decision was taken to immediately perform an operation. Total aortic arch and descending aorta replacement were performed through a median sternotomy with left 5th interspace thoracotomy. The operation was performed under deep hypothermic circulatory arrest, and selective antegrade cerebral perfusion was accomplished. As a result of the exploration of the aortic arch, it was found that the intimal injury by the bare stent caused RTAD. The patient was successfully extubated after the operation and was discharged without any complications. RTAD can present as an early complication after descending stent grafting because of aortic instability or due to the strength of bare stents. Aortic arch and descending aorta replacement after TEVAR via a clamshell incision can be safely performed if RTAD is diagnosed early.
