Staged graft replacement with thoracic endovascular aneurysm repair for an extensive thoracoabdominal aortic aneurysm after total arch replacement

Abstract

Abstract Background Open surgery for thoracoabdominal aortic aneurysm is highly invasive. Staged repair for extensive TAAA is effective because it has low morbidity and mortality, and preserves spinal cord perfusion. An initial total arch replacement can create a proximal landing zone for thoracic endovascular aneurysm repair. Case presentation We performed a staged hybrid thoracoabdominal aortic aneurysm repair after total arch replacement, which consisted of a primary open repair procedure as Crawford Extent III and IV thoracoabdominal aortic aneurysms, and a secondary thoracic endovascular aneurysm repair for the residual lesions for four patients. No spinal cord injury was observed. In one patient, the residual descending aortic aneurysm ruptured six months after the primary open surgery. Conclusions Overall, staged hybrid repair is effective and shows low morbidity and mortality. Secondary thoracic endovascular aneurysm repair should be performed as soon as possible to reduce the risk of residual aneurysm rupture.
