Endovascular Repair With In Situ nEedle feNestration of Left Subclavian Artery to Treat AoRtic Dissection(RISEN STAR):A Multicenter Prospective Trial.

Inclusion Criteria: * Based on Computed Tomography Angiography, it is clearly diagnosed as Stanford B type aortic dissection with a breach close to the left subclavian artery; * The dissection the left subclavian artery, and the proximal landing area is less than 1.5cm. The proximal end of the stent needs to be anchored in zone 2 and the left subclavian needs to be performed arterial revascularization; * Landing area requirements: no dissection, no intermural hematoma, no severe calcification, no aneurysm-like expansion, diameter 21-44mm, distance between left common carotid artery and left subclavian artery≥10mm; * The puncture in situ fenestration technique was used to reconstruct the left subclavian artery; * Signed informed consent; * Age ≥18 years old, ≤85 years old, no gender limit. Exclusion Criteria: * Combined ascending aorta disease or performed ascending aorta surgery before; * Congenital connective tissue disease (Marfan syndrome, etc.); * Patients with renal failure or chronic kidney disease before endovascular repair(eGFR≤30ml/min, Dialysis needed, serum creatinine ≥2.5mg/mL within 30 days before operation); * Cerebral hemorrhage, symptomatic cerebral infarction within 6 weeks before treatment, myocardial infarction within 6 weeks before treatment; * Combined systemic diseases that cannot be controlled by current medical level (Such as severe heart function, lung function or liver function abnormalities, patients with advanced tumors, patients with cachexia, …
