Background: Complicated type B aortic dissections require surgery or thoracic endovascular aortic repair (TEVAR). In this study, we sought to explore the early and mid-term clinical efficacy of TEVAR treatment for Stanford complicated type B aortic dissection. Methods: From January 2012 to October 2017, the medical records and the aortic imaging data of 172 consecutive patients treated by TEVAR were retrospectively reviewed for statistical analysis. Aortic remodeling was evaluated based on the preoperative and one-year postoperative followed-up aortic CTA scan results. We analysed the diameters of the total aortic lumens, True and False lumens diameter and the thrombosis status at different five levels along the descending aorta. Results: The primary technical success rate was 97%, and the clinical success rate was 94.8%. At 1-year of aortic CTA follow-up after TEVAR, the true lumen diameter at the stented descending thoracic aorta increased significantly, the false lumen diameter significantly reduced. The remodeling process was stable with mild changes of true lumen increase and false lumen reduction at the unstented distal part of the descending thoracic and the abdominal aorta. Conclusion: This study confirmed that TEVAR treatment for complicated type B aortic dissection has a low mortality rate of mid-term follow-up outcomes. TEVAR stabilizes the size of the aorta and precipitates in FL thrombosis. However, FL in the abdominal aorta still patented and must be carefully observed for further long-term events.
