Objective  To analyze the etiologies, surgical treatment and outcomes of retrograde type A aortic dissection (RTAD) after thoracic endovascular aortic repair (TEVAR) for Stanford type B aortic dissection. Methods  The clinical data of patients with RTAD after TEVAR for Stanford type B aortic dissection receiving operations in Changhai Hospital from March 2014 to August 2018 were analyzed. All patients were followed-up by clinic interview or telephone. Results  A total of 16 patients were enrolled, including 13 males and 3 females with a mean age of 49.1±12.2 years. The main symptoms of RTAD were chest pain in 12 patients, headache in 1 patient, conscious disturbance in 1 patient, and asymptomatic in 2 patients. All the 16 patients received total arch replacement with the frozen elephant trunk technique. Bentall procedure was used in 2 patients, aortic root plasticity in 10 patients and aortic valve replacement in 1 patient. The primary tear in 10 patients was located in the area which were anchored by bare mental stent, and in the other 6 patients it was located in the anterior part of ascending aorta. The mean cardiopulmonary bypass time was 152.2±29.4 min, aortic cross-clamping time was 93.6±27.8 min and selective cerebral perfusion time was 29.8±8.3 min. There was no death in hospital or within postoperative 30 days. The follow-up period was 32-85 (57.4±18.3) months. No death occurred during the follow-up period. One patient underwent TEVAR again 3 years after this operation and had an uneventful survival. Conclusion  Total arch replacement with the frozen elephant trunk technique is a suitable strategy for the management of RTAD after TEVAR for Stanford type B aortic dissection.
