ABSTRACT Objective To identify risk factors and develop a predictive model for retrograde type A dissection (RTAD) following thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD). Methods We analyzed TBAD patients who underwent TEVAR from 2014 to 2024 (IRB:No. TJ-IRB20230805). Patients developing RTAD within 1 year were matched with controls by age, sex, operation date, and location. Logistic regression identified risk factors, and a nomogram was constructed.
