False lumen embolization and false lumen stent-graft techniques for ruptured post-dissection thoracoabdominal aneurysm.

This report details the successful endovascular repair of a ruptured thoracoabdominal aortic aneurysm in a patient with chronic type B aortic dissection. The procedure consisted of thoracic endovascular aortic repair, abdominal endovascular aortic repair, false lumen (FL) embolization with Candy-Plug, and FL stent-graft technique. The approach effectively regulated FL inflow, achieving complete FL closure. The patient was discharged without major complications including spinal cord ischemia or renal failure, and the long-term outcome is also favorable with reduction of the aneurysm size. The follow-up results have shown a reduction in the aneurysm size. This less invasive method could be an option of treatments for post-dissection thoracoabdominal aortic aneurysms, especially in ruptured cases.
