Study on the Safety and Efficacy of the Aortic Arch Single Branch Covered Stent System for Aortic Dissection Involving the Aortic Arch
The objective of the study is to evaluate the Safety and Efficacy of Aortic Arch Single Branch Covered Stent System for Aortic Dissection Involving the Aortic Arch
• Age between 18 and 80 years, gender unrestricted.
• Patients are diagnosed with Stanford Type B aortic dissection and need revascularization of the left subclavian artery.
• Anatomical criteria:
‣ The diameter range of the proximal aortic landing zone is 20-42 mm.
⁃ The length of the proximal aortic landing zone (the distance from the posterior edge of the left common carotid artery orifice to the first intimal tear) is ≥15 mm.
⁃ The distance between the left common carotid artery and the left subclavian artery is ≥5 mm.
⁃ The length of the left subclavian artery landing zone is ≥25 mm, and the diameter range of the landing zone is 5-15 mm.
⁃ Suitable access to the femoral artery, iliac artery, and upper limb artery.
• Patients understand the purpose of the study, volunteer to participate, and are willing to complete follow - up visits as required by the protocol.
