Interrupted fourth aortic arch with persistent fifth aortic arch and aortic coarctation—treatment with balloon angioplasty combined with surgery

Abstract

AbstractA symptomatic neonate was referred for aortic coarctation and, at cineangiography, was shown to have an interruption of the aortic arch at the isthmus together with coarctation related to a persistent fifth aortic arch. Balloon dilation of the coarctation was performed, but the coarctation was still evident after six months. A graft was then interposed between the left subclavian artery and the descending aorta. Balloon dilation was repeated five years later leaving a residual gradient of 11 mm Hg.
