Objective To discuss the application of double parallel stent for preserving arch branch vessels during thoracic endovascular aortic repair. Methods During the period from June 2015 to June 2016, double parallel stents were carried out in 9 cases at department of vascular surgery, the People′s Hospital of Xinjiang Uygur Autonomous Region. Results One patient died of an acute ischemic stroke and subsequently resulted in multiple organ failure after thoracic endovascular aortic repair. Eight patients received an aorta CT angiography during follow up at 1, 3, 6 months. During follow up, the patency rate for double parallel stents was 100%. There were no endoleak in 8 cases. Conclusion Double parallel stents are suited to patients with emergency situation and unsuited to open surgery in complicated aortic arch pathologies. Surgical approach is determined by preoperative evaluation. Prevention of endoleak and stroke is important in all cases. Key words: Aorta; Stents; Heart
