Palavras-chave: Angiografia, revascularização miocárdica, artéria torácica interna.

A técnica de Vineberg consiste no implante da artéria torácica interna (ATI), sem a ligadura dos seus ramos, diretamente na musculatura do ventrículo esquerdo. Nos últimos 8 anos, temos utilizado com sucesso o procedimento de Vineberg modificado pelo autor1, obtendo uma baixa morbimortalidade e uma alta taxa de perviedade do enxerto2, em mais de 60 pacientes que não puderam submeter-se a cirurgia de revascularização direta do miocárdio com anastomose ATI na artéria interventricular anterior (AIA). Nestes casos incomuns, a AIA apresentava-se, na grande maioria dos casos, hipoplásica e com doença ateromatosa difusa, incompatível com a realização de endarterectomia e revascularização direta ou procedimentos angioplásticos. Como última tentativa terapêutica, conforme descrito na literatura atual3-5, dispõe-se da cirurgia de Vineberg. No que concerne à angiogênese, uma das justificativas para a eficácia do procedimento de Vineberg, a literatura registra demonstração da indução de angiogênese em miocárdio isquêmico humano e outros trabalhos sugerem benefícios da associação deste procedimento à terapia angiogênica6-10. Acreditamos que, no futuro próximo, contaremos com essa poderosa combinação para tratamento destes pacientes.

The Vineberg procedure comprises implantation of the internal thoracic artery (ITA), without ligating the intercostal side branches, directly into the left ventricle muscle. Over the past 8 years, we have successfully used the Vineberg technique which was modified by the senior author1, obtaining low morbidity and mortality rates and high graft patency rates2, in more than 60 patients who were unable to undergo direct myocardial revascularization with ITA anastomosis to the anterior interventricular artery (AIA). In the majority of these unusual cases, the AIA was hypoplastic, with difuse atheromatous disease, which is incompatible with an endarterectomy procedure and direct revascularization or angioplastic surgery. As per current literature, the Vineberg procedure is a last resort therapeutic option3-5. In regard to angiogenesis, which is one of the justifications for the efficacy of the Vineberg procedure, the medical literature demonstrates the induction of angiogenesis in an ischemic human myocardium; other studies suggest a beneficial association of this procedure with angiogenic therapy6-10. We believe that in the near future, patients will be able to profit from this powerful treatment combination.
