1 Double Aortic Arch With Ascending Aortic Aneurysm and Aortic Valve Regurgitation 
Yiwu Liang, MD, Qiwen Zhou, MD, Ziying Chen, MD  The Annals of Thoracic Surgery  Volume 97, Issue 2, Pages e43-e45 (February 2014) DOI: /j.athoracsur Copyright © 2014 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 An anterior perspective preoperation image (three-dimensionally reconstructed computer tomography scan of the heart and great vessels) shows the ascending aorta divided into almost balanced right and left aortic arches. Left and right subclavian and carotid arteries arose from each corresponding side of arch. The aortic root is enlarged and aneurysmal, associated with severe aortic valve regurgitation. (AO = aorta; LAA = left aortic arch; LCC = left common carotid artery; LSA = left subclavian artery; PA = pulmonary artery; RAA = right aortic arch; RCC = right common carotid artery; RSA = right subclavian artery.)

3 Fig 2 A posterior perspective preoperation image (three-dimensionally reconstructed computer tomography scan of heart and great vessels) shows that each arch gave origin to the common carotid and subclavian artery, and joined together posterior toward the right side of the chest to form a right descending aorta. (DA = descending aorta; LAA = left aortic arch; LCC = left common carotid artery; LSA = left subclavian artery; RAA = right aortic arch; RCC = right common carotid artery; RSA = right subclavian artery.)

4 Fig 3 An anterior perspective postoperation image (three-dimensionally reconstructed computer tomography scan of heart and great vessels) shows the aortic root was replaced. The aortic valve was replaced by a mechanical valve; the ascending aorta was replaced by an artificial conduit vessel; the newly reconstructed ascending aortic conduit was reconnected with the right arch. The left arch was reconnected with the newly reconstructed ascending aorta through another new artificial conduit vessel. The inner space of the vascular ring was then enlarged. (LAA = left aortic arch; LCC = left common carotid artery; LSA = left subclavian artery; NCAV = newly constructed artificial vessel; NRAA = newly reconstructed ascending aorta; RAA = right aortic arch; RCC = right common carotid artery; RSA = right subclavian artery.)

5 Fig 4 A posterior perspective postoperation image (three-dimensionally reconstructed computer tomography scan of heart and great vessels) shows reconstruction of the arch vessels. (DA = descending aorta; LAA = left aortic arch; LSA = left subclavian artery; NCAV = newly constructed artificial vessel; RAA = right aortic arch; RCC = right common carotid artery; RSA = right subclavian artery.)
