Description
Summary:Coronary subclavian steal syndrome is an uncommon cause of ischemia recurrence after coronary artery bypass grafting. Endovascular treatment of subclavian artery stenosis or occlusion is increasingly common and appears to offer a safe and effective alternative to surgical revascularization. We report a case of recurrent angina after coronary artery bypass grafting for critical subclavian artery stenosis. The anomalous origin of the vertebral artery from the aortic arch was an indication for endovascular treatment. We discuss the diagnostic difficulties and the management pitfalls of subclavian artery angioplasty in this syndrome. Resumo: A síndrome de roubo da subclávia é uma causa incomum de recidiva de isquemia após a cirurgia de revascularização do miocárdio (CABG). A terapêutica endovascular da estenose ou oclusão da artéria subclávia é cada vez mais usada e parece oferecer uma opção segura e efetiva à revascularização cirúrgica. Apresentamos o caso de uma angina recorrente após CABG devida a estenose arterial crítica da subclávia. A origem anómala da artéria vertebral a partir da crossa da aorta favoreceu o tratamento endovascular. Discutimos as dificuldades diagnósticas e as dificuldades do tratamento da angioplastia da artéria subclávia durante essa síndrome.
