Resumo Background. Acute aortic dissection is a lifethreatening medical condition that is associated with high morbidity and mortality.Methods. of 198 patients treated with a self-expanding polyester-covered stent-graft for various pathologic aortic conditions in our institution, we selected 70 consecutive patients with type B aortic dissection who were undergoing treatment. the stent-graft was introduced through the femoral artery in the angiography suite, under general anesthesia with systemic heparinization and induced hypotension.Results. the procedure was performed in 70 patients; of these, 58 had descending aortic dissection and 12 had atypical dissections. the procedure was successful in 65 patients (92.9%), as documented by exclusion of the false lumen of the thoracic aorta. Eleven patients (18.9%) had persistent blood flow in the false lumen of the abdominal aorta due to distal reentries. Five patients (7.1%) underwent conversion to surgery. Insertion of additional stent-grafts was required in 34 patients (48.6%). At 29 months of follow-up, 91.4% of the patients were alive.Conclusions. Stent-grafts are an important means of treating aortic dissections, which may replace conventional medical treatment of this condition for the majority of patients.
