JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP 1299 OP 1300 VO 4 IS 10 A1 Arriero, JM A1 Gil, J A1 Martin, C A1 Mainar, V A1 Romero, S YR 1991 UL //www.qdcxjkg.com/content/4/10/1299.abstract AB A young man with congenital absence of the left pulmonary artery is reported. A right aortic arch and normal pulmonary pressures essentially rule out an alternate diagnosis of occlusive chronic thrombus in the central pulmonary arteries. Recurrent or massive haemoptysis makes an exact knowledge of the pulmonary circulation advisable.
