The primary objective of this study is to evaluate the safety and efficacy of the TEVAR combined with extended bare-metal stenting (distal landing zone ≥2 cm below renal arteries) in patients with acute complicated type B aortic dissection (ATBAD). Additionally, to prevent postoperative true lumen hypoperfusion in residual thoracoabdominal aortic dissection (visceral zone, infrarenal aorta, and iliac arteries) and persistent ischemic manifestations in visceral and lower extremity arteries post-endovascular repair, extended bare-metal stents are deployed to maintain adequate distal true lumen patency. This strategy ensures perfusion to visceral branches and lower limbs while preparing for future complete endovascular aortic repair.
