Stent dislodgement in the treatment of left main coronary artery dissection.

Correspondencia: George Cesar Ximenes Meireles • Rua Sena Madureira, 1265/102, Vila Clementino, CEP 04021-051, Sao Paulo, SP – Brasil E-mail: gcxm@cardiol.br, george.ximenes@terra.com.br Artigo recebido em 17/09/12, revisado em 21/12/12, aceito em 08/01/13. Palavras-chave Arterias Coronarias, Disseccao, Angioplastia Coronaria com Balao, Stents. Introducao A disseccao acidental do tronco da arteria coronaria esquerda (TCE) e uma das complicacoes mais temidas pelo cardiologista intervencionista, cuja ocorrencia pode ter consequencia grave se nao diagnosticada e tratada prontamente com a revascularizacao miocardica. A incidencia da disseccao ocasionada pelo cateter e menor que 0,1%, elevando-se para 1,05% em pacientes com lesao obstrutiva do TCE1-4. A realizacao de intervencao percutânea imediata com implante de stent parece ser a medida apropriada para tratamento de disseccao acidental do TCE de moderada/ grande extensao, como demonstrado no presente caso.
