“…However, both techniques preserve the structure of the hypoplastic aortic arch, which may result in limited growth or retraction of the area around the anastomosis, causing recoarctation [12], or which may permanently sacrifice the left subclavian artery with the consequent growth deficit in the superior left limb and the consequences that this may cause [13]. Other authors prefer to treat this anomaly as an interruption of the aortic arch, using sternotomy, cardiopulmonary bypass and deep hypothermia [8]. In our view, this procedure is not necessary, except in the case of associated intracardiac abnormality, which may require single stage correction.…”
