Purpose: To describe a possible application of thoracic false lumen occlusion techniques with a Candy-Plug occluder to induce false lumen thrombosis for preconditioning the spinal cord during staged fenestrated repair of postdissecting thoracoabdominal aneurysms. Technique: A Candy-Plug occluder is deployed within the thoracic false lumen after proximal entry tear coverage with a standard thoracic stent-graft during staged repair of postdissecting thoracoabdominal aneurysms. The blockade of thoracic false lumen retrograde reperfusion from distal entry tears induces a controlled thrombosis of both the thoracic false lumen and intercostal arteries. Then, when the fenestrated device is delivered 4 to 6 weeks later, the procedure is completed with standard techniques according to the staging protocols of individual centers. Conclusion: A new possible application of a Candy-Plug false lumen occlusion technique might be an intermediate procedure aimed at preconditioning the spinal cord by occluding the thoracic false lumen during complex staged fenestrated thoracoabdominal repairs.
