Safety and Efficacy of TEVAR Combined With Long Bare-metal Stents in the Intervention of ATBAD

"\- Primary TEVAR: Primary TEVAR: Employ Carstor® 70-240mm, AnkuraTMⅡ60-200mm, WeFlow-TbranchTM 160-240mm endograft deployed with ≥2cm proximal landing zone coverage.~Concurrent bare-stenting: Post-TEVAR femoral access deployment of Fabulous® (45-150mm) long bare-metal stent with:~Proximal overlap ≥3cm with TEVAR graft. Distal extension 2-6cm below renal artery plane. Maximum distal limit: above iliac bifurcation.~\- Intraprocedural angiography with spinal reference mapping guides precise stent positioning relative to visceral arteries and infrarenal aorta."
