Transcatheter Embolization of Systemic-to-pulmonary Artery Fistulas: a Case Report

Abstract The systemic artery to pulmonary vessel fistula(SAPVF) is an uncommon vascular abnormal communication between systemic arteries (except bronchial arteries) and the lung parenchyma[1]. It can be divided into congenital and acquired causes. Congenital SAPVF is often accompanied by cardiac or pulmonary artery hypoplasia, and acquired are usually caused by pleural adhesions after pleurisy, empyema, trauma, or surgery[2].We report a case of transcatheter arterial embolization for the treatment of congenital right inferior phrenic artery to pulmonary artery fistula.
