title: Selective Embolization of Systemic Collaterals for the Treatment of Recurrent Hemoptysis Secondary to the Unilateral Absence of a Pulmonary Artery in a Child.
abstract: The unilateral absence of the pulmonary artery (UAPA) is a rare anomaly. Hemoptysis due to systemic collaterals is one of the most common complications of UAPA. To the best of the authors' knowledge, the utility of selective embolization for the treatment of this condition in children has not been reported previously. This report describes a 6-year-old girl with isolated UAPA (IUAPA) admitted for a 10-month history of recurrent hemoptysis that had worsened during the previous 2 months. Selective embolization of the bronchial systemic collaterals was performed. The patient remained asymptomatic with no recurrence of hemoptysis 8 months after the procedure.
