  • Title: [Total arch replacement through a mediansternotomy for an aortic arch aneurysm with an aberrant right subclavian artery].
    Author: Tanaka H, Hamada M, Higuchi S, Itoh T.
    Journal: Kyobu Geka; 2011 Dec; 64(13):1158-61. PubMed ID: 22242293.
    Abstract:
    The patient was a 77-year-old man. In 2004, he developed thrombosed aortic dissection extending from the distal aortic arch to the renal artery bifurcation. He was discharged after his condition improved with conservative treatment. He was followed up as an outpatient because there was an aneurysm, which measured 50 mm in diameter, at the aortic arch. Thereafter the aneurysm gradually enlarged. In May 2009, computed tomography (CT) showed that the aneurysm had increased to 10 cm in diameter and the patient began to have back pain. Thus, surgery was planned. CT revealed that the right subclavian artery originated distal to the left subclavian artery and coursed posterior to the esophagus and trachea. Surgery was performed using median sternotomy. Arch replacement and right subclavian artery reconstruction were performed under hypothermic circulatory arrest with selective cerebral perfusion. The right subclavian artery was controlled at the right border of the trachea, and cerebral perfusion was performed at this site. An end-to-side anastomosis to the reconstructed right common carotid artery was performed by an anterior tracheal approach. The patient had no cerebral complications and his postoperative course was uneventful.
