    Journal: Arq Bras Cardiol; 2024; 121(5):e20230780. PubMed ID: 38896590.
    Abstract:
    In coronary artery bypass grafting (CABG) the use of the internal thoracic artery (ITA), is a Class I indication for the left anterior descending (LAD) artery. Atherosclerosis is a systemic disease, and peripheral arterial disease (PAD) is an important complicator of CABG, present in about one-third of the patients with coronary disease. In Leriche Syndrome, ITA can be the source of collateral circulation for arteries below the level of occlusion. Its inadvertent use can lead to serious ischemic complications in the dependent territories. Na cirurgia de revascularização do miocárdio (CRM), o uso da artéria torácica interna (ATI), é uma indicação de Classe I para a anastomose com a artéria descendente anterior esquerda (ADA). A aterosclerose é uma doença sistêmica, além da doença coronariana, um terço dos pacientes possuem doença arterial obstrutiva periférica (DAOP), que é um complicador da CRM. Na Síndrome de Leriche, a ATI pode ser fonte de circulação colateral para artérias abaixo do nível de oclusão. O seu uso inadvertido pode levar a complicações isquêmicas graves nos territórios dependentes.
