Pulmonary steal syndrome: an unusual case of coronary-bronchial pulmonary artery communication.
The authors report a patient with angina pectoris in whom selective left coronary angiography demonstrated that the pulmonary artery branch to an apical lung segment was supplied by a bronchial collateral vessel which arose from the left circumflex artery. The anatomic and physiological developmental mechanisms, and the clinical implications, are discussed. Relief of the patient's angina following ligation of the pulmonary artery branch indicated the development of a form of pulmonary steal syndrome.
