ABSTRACT

A case never described in adults before is here reported. A 35-year-old patient who had referred precordial pain in effort for seventeen years was investigated after having been submitted to correction of coarctation of the aorta, and had the following diagnosis: anomalous origin of the circunflex artery. In the intraoperatory, the latter was found to proceeed from the right pulmonary artery. The anomalous ostio was sutured and a free graft was made, from the right internal thoracic artery to the circunflex coronary. In addition to the unusualness of such pathology, some physiopatologic considerations related to the coarctation of the aorta may be made, in this particular case.

RESUMO

É relatado, pela primeira vez na literatura, o caso de paciente adulto de 35 anos, com queixa de dor precordial aos esforços desde há 17 anos e que, após ter sido submetido a correção de coarctação de aorta, foi investigado e teve como diagnóstico: origem anômala da artéria circunflexa. No intra-operatório, constatou-se que a mesma tinha origem na artéria pulmonar direita. Foi realizada a sutura do óstio anômalo e um enxerto livre da artéria torácica interna direita para a coronária circunflexa. Além da raridade da lesão, são possíveis considerações fisiopatológicas relacionadas com a coarctação da aorta, neste caso específico.
