The application of short stent in root of aorta for the treatment of Stanford type A aortic dissection

Abstract

Objective: To explore the effect of implanting short stent in root of aorta for the treatment of Stanford type A aortic dissection. Methods: Clinical data of 39 patients with Stanford type A aortic dissection who underwent surgical procedure at the Department of Cardiovascular Surgery of Luoyang Central Hospital Affiliated to Zhengzhou University, between January 2013 and December 2015 were retrospectively analyzed. There were 31 males and 8 females aged 27 to 75 (49.3±10.3) years. All patients received short stent implanting in aortic root, total arch replacement and stented elephant trunk implantation were performed at the same time. Results: All the operations were successfully performed. Two patients died during hospitalization. Four patients underwent reexploration for postoperative bleeding. Postoperative mortality was 5.1%(2/39). Follow-up duration was 3 to 24 months, with a median time of 14 months. One patient died of lung infection, gastrointestinal bleeding and renal faliure during follow-up. Conclusion: Patients with aortic intimal tear located at higher root of aorta may be suitable for short stent implanting, and the procedure has satisfactory clinical outcomes.
