          Abstract

          A 54-year male with previous triple vessel coronary artery and aorto-bifemoral bypass graft surgeries complained of crescent angina. Stress induced myocardial ischemia on echocardiography was demonstrated. We performed direct stenting of a saphenous vein graft to the right coronary artery, via right radial approach. Subsequently stenting of a severe left subclavian artery proximal stenosis was performed via right brachial approach in order to relieve an overt myocardial ischemia in the territory supplied by a patent left internal mammary artery graft originated distally to the left subclavian stenosis. The finding of a total left axillary artery occlusion complement the pathogenesis of myocardial ischemia produced by limited anterograde flow and not driven by the common flow reversal mechanism of a typical coronary-subclavian steal syndrome.

          Se trata de un paciente masculino de 54 años de edad, con antecedentes de cirugía de revasuclarización miocárdica por enfermedad coronaria trivascular, así como puentes aortobifemorales. Se presentó en nuestro centro aquejando de angina de pecho, de patrón creciente. Se demostró la existencia de isquemia miocárdica, mediante ecocardiografía con estrés farmacológico. Realizamos una angioplastia con stent a un puente de safena inversa a la coronaria derecha por vía radial derecha. Posteriormente debido a una estenosis proximal severa de la arteria subclavia izquerida, implantamos un stent mediante vía braquial derecha, con la idea de mejorar la isquemia existente en el territorio previamente revascularizado por un puente de arteria mamaria izquierda, que se originaba distalmente a la estenosis de la arteria subclavia. El hallazgo de una oclusión total crónica a nivel de la arteria axilar izquierda completó la patogénesis de la isquemia miocárdica no condicionada por robo al flujo coronario, como tradicionalmente sucede en el síndrome de robo subclavio coronario. En este caso particular, el mecanismo isquémico fue debido al compromiso anterógrado de flujo, provocado por la estenosis severa de la arteria subclavia.
