title: Pulmonary artery agenesis associated with coronary collaterals among adults.
abstract: Unilateral agenesis of the pulmonary artery is a rare congenital anomaly, which commonly involves the right side. Cases are associated with systemic collaterals, that may also rarely arise from the coronary arteries.Two adult patients are presented with a right pulmonary artery agenesis associated with collaterals from the right coronary artery. The implications of such an anomaly on pulmonary artery pressure and lung pathology differs among both cases. The association of coronary collaterals is rare and its implication is variable among various patients.
