Comparision of the long-term outcome of open surgical repair with the thoracic endovascular repair for ;the complicated type B dissection / 实用医学杂志

ABSTRACT

Objective To compare the long-term efficacy of the traditional open surgery (OSP) with the thoracic endovascular aneurysm repair (TEVAR) in the treatment of patients with the complicated Stanford B aortic dissection. Methods The retrospective analysis of the clinical data was conducted in 118 patients (OSP 45 vs. TEVAR 73) with the complicated type B aortic dissection from January 2004 to January 2015. The long-term survival rate was compared between the two groups and the influencing factors of the postoperative survival was analyzed by using the Cox-regression analysis. Results Significant differences in age, sex and operation time were observed between the two groups (P 0.05). The refractory hypertension and preoperative aortic overall diameter > 55 mm were the risk factors for the long-term survival (P = 0.021, OR = 11.1, 95%CI1.428 ~ 86.372; P = 0.001, OR = 4.5, 95%CI 1.842 ~ 11.346). Conclusions Compared with OSP, no obvious advantage of TEVAR was shown in the ten-year overall cumulative survival. In view of the influence factors of refractory hypertension and the aortic diameter for the long-term survival , we should pay attention to the blood pressure control and the performance of endovascular repair technology whether pre- or post-operation.
