The main indications for transluminal thoracic stent-grafting included: persistent pain in spite of medical therapy, signs of distal limb ischemia, signs of aortic rupture, progression of aneurismal dilation of the descending aorta during follow-up (defined as a diameter > 50 mm) and the diameter of descending thoracic aorta of 40mm or larger at the onset of aortic dissection. Data were analyzed statistically; all p-values were two-tailed and differences < 0.05 were considered to indicate statistical significance. Continuous variables were expressed as mean (± SD), and medians were compared by the Student's t test. Differences in categorical variables between the groups were analyzed by the Chi-square or Fisher's exact test.RESULTS: The procedure presented primary technical success in 82.6% of patients. Four patients (17.4%) had an incomplete proximal entry seal. Three patients (13%) died within 30 days of the procedure and eight patients (34.8%) died after 30 days.CONCLUSION: Endovascular correction of complicated Stanford type B aortic dissections is a feasible and effective treatment option. 2011 artículo científico 0102-7638 https://www.redalyc.org/articulo.oa?id=398941881016 en http://www.redalyc.org/revista.oa?id=3989 Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery application/pdf Sociedade Brasileira de Cirurgia Cardiovascular Revista Brasileira de Cirurgia Cardiovascular/Brazilian Journal of Cardiovascular Surgery (Brasil) Num.2 Vol.26 |
