title: Unilateral pulmonary artery agenesis presenting with hemoptysis: treatment by embolization of systemic collaterals.
abstract: Systemic-to-pulmonary collateral vessels and shunts develop in patients with isolated unilateral absence of a pulmonary artery (IUAPA). Two cases of IUAPA (right and left) with hemoptysis in adult life are presented. Selective embolization of these systemic vessels controlled hemoptysis successfully. These cases represent an example of an alternative treatment for this rare anomaly.
