Summary: To explore the safety and efficacy of thoracic endovascular aortic repair (TEVAR) in the treatment of patients with type B aortic dissection, and to evaluate the risk factors for long-term mortality. Our study retrospectively evaluated 729 patients with type B aortic dissection, who were divided into the thoracic endovascular aortic repair group and the optimal medical treatment group according to their treatment. In-hospital mortality, death within 30 days, and aortic-related mortality were lower in the thoracic endovascular aortic repair group than in the optimal medical treatment group (p < 0.05). The cumulative overall survival rates for the thoracic endovascular aortic repair group at 1 year, 5 years, and 10 years were 92.5%, 84.1%, and 73.5%, respectively. The Cox analysis found that TEVAR was beneficial in reducing mortality and that a vertical length of the dissection exceeding 150 mm was a risk factor for mortality.
