Endovascular Treatment in the Subclavian Steal Syndrome

Abstract

When the proximal occlusion or stenosis of the subclavian or of the brachiocephalic artery may require distal arterial filling through reversal flow from the vertebral artery, causing clinically significant blood supply reduction to the brainstem, it is called subclavian steal syndrome (SSS). We report a 54-year-old male patient who presented with multiple episodes of syncopes and vascular claudication due to right SSS. He underwent an angioplasty, evolving with complete improvement of the symptoms. We review the clinical presentation, the diagnostic methods, and the treatment options of the disease.

RESUMO

A oclusão ou estenose da artéria subclávia ou do tronco braquiocefálico pode exigir fluxo reverso pela artéria vertebral para seu enchimento distal, causando sintomas devido à redução de fluxo no tronco encefálico. A isso se dá o nome de síndrome do roubo da subclávia. Relatamos o caso de um paciente de 54 anos com múltiplos episódios de síncope e claudicação vascular por síndrome do roubo da subclávia à direita, submetido a angioplastia e evoluindo com melhora completa dos sintomas. Revisamos a apresentação clínica, métodos diagnósticos e opções de tratamento da doença.
