ABSTRACT

The purpose of this study is to report two surgical cases, whereby after the repair of the left ventricular aneurysm, the myocardial revascularization of the interventricular anterior artery (IAA) was not possible. Using the left internal thoracic artery it was decided to perform anastomosis with the interventricular anterior (IAA) and its cephalad ligation, in order to obtain a retrograde flow and to avoid an arteriovenous fistula formation. There was no mortality and the results are optimistic in a short follow-up of these two patients. Myocardial perfusion tests and pre and post-operative angiography of the coronary system and the left internal thoracic artery are assessed and discussed. The geometrical reconstruction of the left ventricle and the revascularization of the ischemic areas play major role in the repair of postinfarction ventricular aneurysm. When it is not possible to access diretly the revascularization of the IAV this technique is safely and easily perfomed and shows satisfactory results in a short period of time.

RESUMO

O objetivo deste trabalho é referir dois casos cirúrgicos, onde, após ressecção de aneurisma de ventrículo esquerdo, a revascularização do miocárdio através da artéria interventricular anterior (AIA) não foi possível. Utilizando-se a artéria torácica interna (ATI) esquerda, optou-se pela anatomose com a veia interventricular anterior (VIA) com ligadura próxima, para estabelecimento do fluxo retrógrado e evitar a formação de fístula artenovenosa. Não houve mortalidade e os resultados a curto prazo são encorajadores. Testes de perfusão miocárdica com radioisótopos no pré e no pós-operatório, assim como angiografia do sistema coronário e da artéria torácica interna esquerda pré e pós-operatória são apresentados e discutidos. O objetivo da cirurgia de aneurisma ventricular é a recomposição geométrica do ventrículo esquerdo e revascularização de possíveis áreas isquémicas. Na impossibilidade de revascularização direta da artéria interventricular anterior, a técnica citada demonstra ser facilmente exeqüível e, a curto prazo, com bons resultados.
