An 81-year-old man complaining of
back pain was admitted. Computed tomographic scan revealed an
aortic arch aneurysm and an abnormal retroesophageal artery.
It was believed to be an aberrant right subclavian artery. The
diagnosis was confirmed by angiogram. Although there was no evidence
of rupture, his back pain prompted us to perform emergency surgery.
Through median sternotomy using a cardiopulmonary bypass, systemic
hypothermia and selective cerebral perfusion, total arch replacement
was done. There was evidence of impending rupture, which was
probably the cause of his back pain. The proximal portion of
the aberrant right subclavian artery was severely calcified,
so the right subclavian artery was reconstructed. It was anastomosed
with one branch of the arch graft which passed the anterior of
the trachea. The postoperative course was uneventful. We believe
median sternotomy was a proper approach for such a situation.
