title: Patent ductus arteriosus associated with aberrant right subclavian artery: two cases, one successful interventional closure of PDA﻿.
abstract: ﻿Two children were sent to the catheterization laboratory for transcatheter closure of patent ductus arteriosus (PDA). During the intervention, cineangiogram revealed associated aberrant right subclavian artery (ARSA). Both patients had left-sided aortic arch. The first patient was sent to surgery after one unsuccessful attempt to close the PDA due to the proximity of the ARSA and also because of other concomitant cardiac lesions. We successfully treated the second patient by closing the PDA with a Nit-Occlud® PDA occlusion device (Pfm Medical, Carlsbad, California). Similar mirror cases of PDA closure with aberrant left subclavian artery and right aortic arch have been reported. Anatomic features, as well as the technique and management of the procedure, are discussed here.
