[Hemoptysis in a patient with acquired anomaly of the arterial vascularization of the lung].

An anomalous systemic pulmonary supply may be acquired and present only one symptom: hemoptysis. The incidence of this pathology is unknown. A case of acquired systemic pulmonary arterialization was observed after surgical intervention of myocardium vascularization with the left mammary artery. The diagnosis was obtained through an arteriography of the left mammary artery. In this case, the therapy consists in ablating the affected parenchyma followed by the interposition of a bovine pericardium patch between the mammary artery and the remaining pulmonary tissue.
