Eligibility
Inclusion criteria
Inclusion criteria: Non-pregnant subjects aged 18 to 85 years old; Patients diagnosed with distal aortic dissection requiring endovascular treatment (the proximal tear of the aortic dissection has been treated, but there is still a dissection tear in the distal descending thoracic aorta and beyond and accompanied by any one or more of the following conditions: patients with distal dissection on the verge of rupture, poor perfusion of branch arteries, dissection-related pain, the maximum diameter of the aorta in the area affected by dissection >50mm, or patients with continued expansion of the dissection false lumen during follow-up)); Subjects judged by the investigator to be suitable for endovascular treatment; Subjects who can understand the purpose of the trial, voluntarily participate and sign the informed consent form, and are willing to follow up; Anatomical conditions: the diameter of the thoracoabdominal aorta is =14mm and =32mm; the number of distal tears is greater than or equal to 2, and the diameter of the tears is =20mm.
Exclusion criteria
Exclusion criteria: Women who are pregnant or breastfeeding; The patient was clearly diagnosed with aorta-related connective tissue disease (such as Marfan syndrome, etc.); The patient has a clear history of allergies to nickel-titanium alloy, platinum-tungsten alloy, contrast media, etc.; Severe liver function abnormalities (alanine aminotransferase or aspartate aminotransferase 2.5 times higher than the upper limit of normal); Hematological abnormalities: leukopenia (WBC<3×10^9/L), acute anemia (Hb<90g/L), thrombocytopenia (PLT<50×10^9/L), history of bleeding or coagulation disorder; Myocardial infarction or stroke in the past month; Cardiac function class IV (NYHA classification); Uncontrolled infection, such as bacteremia or toxemia; Patients who have malignant tumors with life expectancy less than 12 months; The subject is participating in other clinical trials of drugs or medical devices and has not yet completed the primary endpoint of the study; Patients with poor compliance and unable to follow up as planned; Other situations determined by the investigator to be inappropriate for endovascular treatment, such as the lack of suitable vascular access or the inability of the subject to cooperate, etc.
