title: Proximal interruption of the pulmonary artery: Transcatheter embolization for emergent management of massive hemoptysis.
abstract: Transcatheter embolization is the first-line treatment for massive hemoptysis and recurrent intractable hemoptysis. Proximal interruption of the pulmonary artery is a rare congenital anomaly characterized by hypertrophy and neovasculsarity of bronchial and nonbronchial aortopulmonary collaterals; hemoptysis complicates a minority of cases. We present a case of unilateral proximal interruption of the left pulmonary artery associated with a right-sided aorta, presenting in adulthood with hemoptysis. The patient was managed emergently with bronchial, intercostal, and inferior phrenic artery embolization.
