Thoracic endovascular aortic repair: a local single institution experience.

Author information

  • 1Department of Diagnostic Radiology, Tan Tock Seng Hospital, Singapore.



The purpose of this retrospective study was to evaluate the short- to mid-term results of the endovascular repair of thoracic aortic disease and to present an overview of our experience with thoracic endovascular aortic repair (TEVAR) in our institution.


A retrospective review of all patients who were treated and underwent TEVAR in our institution between August 2004 and November 2009 was conducted.


Technical success was achieved in 100% of the patients and the 30-day mortality rate was 0%. Perioperative endoleak was visualised at the end of the procedure in 4 patients. Secondary endoleak was observed in 2 patients. Mean hospital length of stay post-TEVAR was 15.4 days. Postoperative major complications were observed in 4 patients. The 30-day mortality rate was 0%, with 2 mortalities (11.1%) during the followup period.


This study adds to the growing body of literature that support TEVAR as an effective procedure in the management of thoracic aortic diseases and reflects its feasibility in our population. Further technical advancement in stent grafts, careful selection of patients and standardised peri-procedural care would contribute to further improvements in clinical outcomes.
