“…Many groups electively perform this bypass, belatedly, in cases of symptom onset. 17,18 A complication rate of 30.7% was observed in the present study; the femoral artery lesion was the most prevalent complication, in 7.6% of the cases. The large profile devices associated with the hight number of patients who underwent retreatment contributed to these rates in the present study.…”

“…The 'spontaneous resolution' of type I leaks is actually caused by thrombosis of small leaks, which can evolve with the continuous transmission of pressure to the false lumen. The Evaluation of the Medtronic Vascular Talent Thoracic Stent Graft System for the Treatment of Thoracic Aortic Aneurysms (VALOR) study 17 demons trated annual leak rates of 17%, with type I leaks in 6.3%, type II leaks in 9.5%, and type III leaks in 1.9% of the cases.…”

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

“…Considering the cases of spontaneous resolution, the annual rates of reinterventions were 10.3% for G1 and 15.3% for G2. The VALOR study has presented annual leakage rate of 17%, with type I leakage occurring in 6.3% of the cases, type II in 9.5%, and type III in 1.9% (12) . In the Group1, three patients (10.3%) presented leakage as indication for endovascular procedure.…”

“…The VALOR study has demonstrated carotid-subclavian shunt in 5% of cases. Many groups are electively and belatedly submitted to such a shunting, in case symptoms manifest (12) . Avoiding aortic clamping with the endovascular technique reduces the complications by ischemia of the target organ, as well as cardiac (1% versus 10%), respiratory (8% versus28%) and renal complications, as compared with open surgery (13) .…”

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. Keywords: Aneurysm; Vascular graft; Atherosclerosis.Objetivo: Analisar os resultados do tratamento de uma série consecutiva de pacientes submetidos a tratamento endovascular de doenças da aorta torácica. 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.
