Descending and Thoracoabdominal Aortic Aneurysms T2 Cardiac Surgery in the Adult, 4e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-163310-9 LK accesscardiology.mhmedical.com/content.aspx?aid=55926508 RD 2024/04/19 AB Treating aneurysms that arise from the aortic segments distal to the left subclavian artery poses challenges that are distinct from those presented by aneurysms of the more proximal ascending and arch segments. The distal aortic segments comprise the descending thoracic aorta, which extends from the left subclavian artery to the diaphragm within the chest, and the abdominal segment that extends from the diaphragm to the iliac bifurcation. The diaphragm divides the thoracic aorta from the abdominal aorta.
