Aortic dissection and aortic aneurysm are two of the most common catastrophic events involving the aorta. Thoracic endovascular aortic repair is now considered as a promising alternative to open surgical graft replacement. The aim of endovascular repair of a thoracic aneurysm is to exclude, and thus depressurize, the aneurismal wall and the aim of the endovascular repair of type B aortic dissection is to obliterate all of the false lumen through thrombosis after sealing the primary entry tears, thus to ensure the true lumen perfusion. But in some special pathologies, such as when the aneurysm and chronic type B dissection are aligned in tandem, or when a visceral branch originates from the false lumen, how should the endovascular repair strategy proceed in this situation？ For the endovascular stent repair of some special chronic type B aortic dissection, the false lumen cannot be obliterated, and the true and false lumens in the dissected but with a normal diameter distal aorta need to be perfused at the same time, as practiced in the surgery treatment. In this report, we present a case of endovascular stent repair for a special thoracic aneurysm and chronic type B aortic dissection aligned in tandem.
