Mid-Term Results of Left Carotid-Subclavian Bypass in Patients Undergoing Zone 2 TEVAR.

INTRODUCTION: The aim of this study was to present the mid-term results of patients who had undergone a carotid-subclavian bypass surgery after a thoracic endovascular aortic repair (TEVAR) stent-graft implantation with proximal landing at zone 2 of the aorta. METHODS: A total of 66 patients had undergone TEVAR and carotid-subclavian bypass between January 2015 and May 2020 at our clinic. Five of these patients were lost to follow-up, so 61 patients were included in this retrospective study. At follow-up visits, patency of the carotid-subclavian bypass grafts was evaluated with physical examination and radiological imaging. RESULTS: The mean follow-up time was 15.11±12.29 months (ranging from 1 to 56 months). There were 3 (4.91%) in-hospital deaths of patients admitted with bilateral lower limb and visceral malperfusion. There were also 2 (3.27%) deaths unrelated to the procedure. Carotid-subclavian graft occlusion occurred in 3 (4.91%) patients. The occlusion was detected with radiological imaging within a period of 12 to 24 months. The graft patency rate was 100% in the first 12 months. The mean graft patency time (survival) was 52.56±2.10 months. CONCLUSION: Periprocedural carotid-subclavian bypass surgery with synthetic grafts is a recommended procedure with high patency and acceptably low mortality and morbidity rates in TEVAR.

Aberrant right subclavian artery (arteria lusoria) aneurysm with a Kommerell's diverticulum.

The treatment options for aberrant right subclavian artery vary depending on the presence of Kommerell's diverticulum. Because there is a tendency not to report mortalities of these rare cases in the literature, it is hard to reach a conclusion on treatments from the limited data on post-interventional results in these patients. We report our experience with a 67-year old patient with an aberrant right subclavian aneurysm with Kommerell's diverticulum, diagnosed by chance.

As opções de tratamento para artéria subclávia direita aberrante variam dependendo da presença de divertículo de Kommerell. Como há uma tendência a não relatar mortalidade nos raros casos descritos na literatura, é difícil chegar a uma conclusão sobre tratamentos tendo em vista os dados limitados sobre resultados pós-intervenção nesses pacientes. Relatamos aqui nossa experiência com um paciente de 67 anos de idade com aneurisma de artéria subclávia aberrante direita com divertículo de Kommerell diagnosticado ao acaso.

Off-pump Coronary Artery Bypass Grafting in Moyamoya Disease: a Case Report.

Moyamoya disease is a rare, idiopathic, progressive, occlusive disease of the internal carotid artery characterized by the development of collateral vasculature in the brain base. In patients with accompanying coronary artery disease, cardiopulmonary bypass posses a potential risk for perioperative cerebral ischemic complication. Herein, we report a 53-year-old male case of Moyamoya disease and coronary artery disease who was treated with off-pump coronary artery bypass grafting.

The effect of gender on the early results of coronary artery bypass surgery in the younger patients' group / O efeito do gênero sobre os resultados iniciais da cirurgia de revascularização do miocárdio em grupo de pacientes mais jovens

Introduction: In this retrospective study, we aimed to determine the risk factors for coronary artery bypass surgery in patients under 45 years of age, and evaluate the early postoperative results and the effect of gender. Methods: A total of 324 patients under 45 years of age who undergone on-pump coronary artery bypass surgery between April 12, 2004 and January 10, 2012 were included to the study. Patients divided into groups as follows: Group 1 consisted of 269 males (mean age 41.3), Group 2 consisted of 55 females (mean age 41.6). Preoperative risk factors, intraoperative and postoperative data and early mortality rates of the groups were compared. Results: Smoking rate was significantly higher in Group 1. Diabetes mellitus incidence and body mass index were significantly higher in Group 2 (P values P=0.01; P=0.0001; P=0.04 respectively). The aortic cross-clamping and cardiopulmonary bypass time and number of grafts per patient were significantly higher in Group 1 (P values P=0.04; P=0.04; P=0.002 respectively). There were no deaths in either group. Conclusion: We found that gender has no effect on early mortality rates of the coronary bypass surgery patients under 45 years. .

Introdução: Este estudo retrospectivo teve como objetivo determinar os fatores de risco para cirurgia de revascularização do miocárdio em pacientes com menos de 45 anos de idade e avaliar os resultados pós-operatórios precoces e o efeito do gênero. Métodos: Um total de 324 pacientes com menos de 45 anos de idade, que submeteram à cirurgia de revascularização miocárdica entre 12 de abril de 2004 e 10 de janeiro de 2012 foram incluídos no estudo. Os pacientes divididos em dois grupos: Grupo 1, composto por 269 homens (idade média 41,3 anos), Grupo 2, composto por 55 mulheres (idade média 41,6 anos). Fatores de risco pré-operatórios, dados intraoperatórios e pós-operatórios e mortalidade precoce dos grupos foram comparados. Resultados: A taxa de tabagismo foi significativamente maior no grupo 1. Incidência de diabetes mellitus e massa corporal foram significativamente maiores no grupo 2 (valor de P: P=0,01, P=0,0001, P=0,04, respectivamente). O pinçamento aórtico e tempo de circulação extracorpórea e número de enxertos por paciente foi significativamente maior no grupo 1 (valor de P: P=0,04, P=0,04, P=0,002, respectivamente). Não ocorreram mortes em ambos os grupos. Conclusão: O gênero não tem efeito sobre as taxas de mortalidade precoce dos pacientes de cirurgia de revascularização do miocárdio com menos de 45 anos. .
