Shows upfront thoracic endovascular aortic repair improves early and midterm survival in uncomplicated acute type B aortic dissection, indicating potential benefits over medical therapy alone.
Objective: We sought to compare the early and midterm outcomes of thoracic endovascular aortic repair (TEVAR) versus optimal medical therapy (OMT) for uncomplicated acute type B aortic dissection. Methods: Data were analyzed for 200 consecutive patients with uncomplicated acute type B aortic dissection from February 1992 to July 2022, including 147 with initial OMT and 53 undergoing TEVAR at index hospitalization. Baseline, intraoperative, and postoperative data, survival, and (re)intervention were compared between the two strategies. Conclusions: In this single-institution experience, upfront TEVAR performed at index hospitalization for uncomplicated acute type B aortic dissection was associated with improved survival at early and midterm follow-up.
