Resumo 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.

Abstract 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.

Abstract 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.
