Abstract:
A modified muscle-sparing high approach to the thoracoabdominal aorta is described, which improves surgical access for thoracoabdominal aortic aneurysm repair. Since 2000, 16 patients with type I and II thoracoabdominal aortic aneurysms have undergone aortic graft replacement using this approach via the 3(rd) intercostal space. There were no hospital deaths. Three (18.8%) patients had severe postoperative pain requiring prolonged analgesia. This approach is a good alternative to the standard approach via the 6(th) intercostal space.
