“…Aortic dissection and TAAs represent conditions with sometimes catastrophic consequences. Despite the developments in diagnostic methods, operative techniques and intra-and postoperative management, such conditions still constitute major challenges for endovascular surgeons (4) . The concept that aortic diseases could be corrected by endoluminal prostheses positioned within the aorta by means of catheters inserted through the femoral artery has emerged over the past few years.…”

“…Other advantages include lower blood transfusion rate, shorter hospital stay, shorter intensive care unit (ICU) stay and lower costs. The main disadvantage is that such a technique predisposes the patient to a higher number of reinterventions in the medium and long terms (4) . The endovascular intervention involving the thoracic aorta has been poorly compared with open surgery in controlled and randomized clinical studies, but medium and long term post-implantation results have been encouraging, with lower rates of early morbimortality as compared with open surgery (6) .…”

Objective: To analyze treatment outcomes in a consecutive series of patients submitted to endovascular treatment of thoracic aortic disease. Technical success, therapeutic success, morbimortality, rate of perioperative complications and reinterventions were taken into consideration. Materials and Methods: The present retrospective study was developed in a reference center in the period from January 2010 to July 2011, involving patients submitted to endovascular treatment of thoracic aortic disease. The study population was divided into two groups: group 1 (G1) -true thoracic aortic aneurysms, aortic ulcer and pseudoaneurysm; group 2 (G2) -chronic type B aortic dissection. Results: Out of a total of 55 patients, 29 belonged to the G1 and 26 to the G2 group. Mean ages were 66.8 ± 10 and 56.4 ± 7 years, respectively. The technical and therapeutic success reached respectively 86.3% and 68.6% in G1 and 100% and 74% in G2. The perioperative mortality rate was 10.3% in G1 and 19.3% in G2. The reintervention rate was 10.3% in G1 and 15.3% in G2. Conclusion: In the present study, the endovascular treatment of thoracic aortic disease proved to be a feasible method associated with acceptable rate of complications.

Foram observados o sucesso técnico, o sucesso terapêutico, a morbimortalidade e a taxa de complicações perioperatórias e de reintervenções. Materiais e Métodos: Estudo retrospectivo, realizado em um centro de referência, no período de janeiro de 2010 a julho de 2011, em que foram analisados pacientes submetidos a correção endovascular de doenças da aorta torácica. A população foi dividida em dois grupos: grupo 1 (G1) -aneurismas de aorta torácica verdadeiros, úlcera aórtica e pseudoaneurisma; grupo 2 (G2) -dissecção aórtica tipo B crônica. Resultados: Em um total de 55 pacientes tratados, 29 pertenciam ao G1 e 26, ao G2. As idades médias foram 66,8 ± 10 e 56,4 ± 7 anos, respectivamente. Os sucessos técnico e terapêutico foram, respectivamente, 86,3% e 68,6% no G1 e 100% e 74% no G2. A mortalidade perioperatória foi 10,3% no G1 e 7,6% no G2, com taxa de mortalidade anual de 10,3% no G1 e de 19,3% no G2. As taxas de reintervenções foram 10,3% e 15,3%, respectivamente. Conclusão: Em nosso estudo, o tratamento endovascular das doenças da aorta torácica demonstrou ser um método viável e associado a aceitáveis taxas de complicações. Unitermos: Aneurisma; Prótese vascular; Aterosclerose. . Aortic dissection is the most feared condition of the aorta and is twice as frequent as aortic rupture. The mortality rate associated with dissection ranges between 1% and 2% per hour, during the first 48 hours. Risk factors frequently associated with such condition include hypertension, cardiovascular and respiratory diseases. Dissection is three times more frequent in men than in women.

“…7 The main disadvantage of this technique is that it predisposes the patient to an increased number of reinterventions in the medium-and long-term. 8,9 Endovascular treatment of chronic type B aortic dissections is still controversial. The primary debate refers to the possibility of remodelling not occurring after occlusion of the inlet orifice, either because of the incapacity of the prosthesis to expand completely or due to the incapacity of the previously formed haematoma to be reabsorbed by the blood vessel wall.…”

Background: Endovascular repair of aortic diseases is a well-established therapeutic alternative for patients with the appropriate anatomy and/or high surgical risk, as it provides lower morbidity and mortality rates. This study aimed to analyse the outcomes of asymptomatic patients undergoing endovascular treatment of thoracic aortic dissections with an aortic diameter > 5.5 cm or endoleaks. Technical success, therapeutic success, morbidity, mortality, and perioperative complication and reintervention rates were assessed. Methods: The present retrospective study, which was performed at a reference centre from January, 2010 to July, 2011, analysed consecutive patients undergoing endovascular repair of chronic complicated type B aortic dissections based on the Stanford classification. Results: Twenty-six patients were treated. The mean age was 56.4 ± 7 years, and 61.5% were males. Technical and therapeutic success rates were 100% and 74%, respectively. The perioperative mortality was 7.6%, and the mortality rate in the first year of follow-up was 19.3%. The reintervention rate was 15.3%. Conclusions: In the present study, endovascular treatment of chronic type B aortic dissections proved to be a feasible method associated with acceptable perioperative complication rates. The therapeutic success and reintervention rates indicated the
