Síndrome de roubo coronário‐subclávio

Abstract

Coronary‐subclavian steal syndrome is a clinical entity that consists in the ocurrence of reverse blood flow in the internal mamary artery in patients who underwent coronary revascularization using this artery as conduit, due to severe proximal stenosis or occlusion of the subclavian artery. Considered to be a rare syndrome, it's existence is becoming more significant thanks to the common use of the internal mamary artery in coronary revascularization, causing cardiac ischemia and, more rarely, acute myocardial infarction. We reporte the case of a pacient who underwent coronary revascularization with the internal mamary artery, presented with recurrent thoracic pain, who was diagnosed with coronary‐subclavian steal syndrome. The subclavian stenosis was treated with angioplasty and stenting, with complete remission of symptoms.
