title: [Coronary steal syndrome by systemic pulmonary hypervascularization fed by a mammary-left anterior descending artery bypass. Treatment by embolization].
abstract: We report a case of coronary-steal syndrome which occurred after coronary bypass surgery. It was related to systemic hypervascularization of the lung caused by a bronchopathy. The steal syndrome was fed by an ectopic bronchial artery arising from the internal mammary--left anterior descending artery bypass graft. The myocardial ischemia disappeared after hyperselective embolization of the ectopic bronchial artery. The authors outline the rarity of this syndrome and its pathophysiology. They insist on the necessity to perform broncho-systemic arteriography for candidates to coronary surgery, in patients with thoracic diseases which can induce systemic hypervascularization of the lung.
