[Occurrence of New Entry after Thoracic Endovascular Aortic Repair for Retrograde Stanford Type A Aortic Dissection;Report of Two Cases].
2019
: We report 2 cases of occurrence of new entry after thoracic endovascular aortic repair(TEVAR) for retrograde Stanford type A aortic dissection. Preoperative chest computed tomography (CT) demonstrated retrograde Stanford type A acute aortic dissection, and TEVAR was performed for entry closure. In the postoperative period, the aortic diameter was not dilated in either case and the false lumen of the ascending aorta disappeared in the case 2. In the chronic phase, however, Stanford type A acute aortic dissection occurred in both cases. TEVAR for acute aortic dissection to close the intimal tear might be a useful procedure, but it could cause a new aortic dissection. We should make a careful decision on surgical procedures in the retrograde Stanford type A aortic dissection.
