Purpose:To assess the significance of aortic remodeling in prevention late events after thoracic endovascular repair (TEVAR) for dissection. Methods:The study involved 52 patients (41 men; mean age was 59.7±13.3 years) with type B dissections and patent false lumens treated TEVAR between 2004 2011. Of patients, 18 were acute phase rupture (n=1), malperfusion (n=10), diameter over 40 mm at onset (n=3), rapid enlargement lumen (n=4). In chronic setting, indications (n=2), >50 (n=18), (n=13). Aortic evaluated 6 months postoperatively, risk factors multivariate analysis using other pre-, peri-, postoperative factors. Results:Over a 36.0±18.9 months, 19 documented: (n=4), I endoleak erosion stent-graft edges Multivariate revealed that failure to achieve postoperatively only significant factor (hazard ratio 0.20, p=0.037). Patients had higher rate freedom from compared those without (100% vs. 81.5% 1 year 79.3% 48.4% 3 years, respectively). Conclusion:Aortic is prognostic better long-term results
