Between May 2001 and June 2008, the outcome and morphological changes in thoracic aortic lesions of 20 surgical high-risk patients who underwent TEVAR were evaluated. Aortic lesions included 8 (40%) type B dissections, 5 (25%) atherosclerotic aneurysms, 4 (20%) penetrating ulcers and 3 (15%) traumatic aortic ruptures. All patients were classified as American Society of Anaesthesiologists class IV and obtained high scores in both the logistic European System for Cardiac Operative Risk Evaluation, median of 14.5% (range 8.1–65.7%), and the STS Parsonet 95 scoring system, median of 14 (range 10–52). Endovascular stent-graft deployment was technically successful in all cases. No surgical conversion occurred. Early mortality was observed in two patients. Clinical and imaging follow-up was available in all patients at a median time of 28 months (range 4–89 months). Overall actuarial survival was 90% at one and five years and 60% at seven years. Mean diameter of the descending aorta decreased from 51.1±13 mm to 45.3±8 mm (P=0.032). Mean reduction in dimension of aneurysms was 10.7±8 mm. Endovascular thoracic aorta repair will probably benefit more patients with multiple comorbidities that limit their life expectancy than patients with a lower profile.
