Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with Stanford type B aortic dissection are treated with Fabulous Thoracic Aortic Stent System in the real world.

Description

Inclusion Criteria:

  1. ≥18 years old, regardless of gender;

  2. Fabulous thoracic aortic stent System is suitable for the treatment of acute or subacute Stanford type B dissection, and the lesions meet one of the following criteria:

    1. It is necessary to treat distal lesions due to the presence of distal tears;
    2. The dissection involved a wide range, and there was collapse of the distal true cavity;
    3. Dissection combined with poor perfusion of distal branch vessels.
  3. With appropriate arterial access and suitable for endovascular aortic repair;
  4. Subjects could understand the purpose of the trial, volunteered to participate in the study, signed the informed consent form by themselves or their legal representatives, and were willing to complete the follow-up as required by the protocol.

Exclusion Criteria:

  1. Patients have participated in clinical trials of other drugs or medical devices related to target lesion treatment or have participated in clinical trials of other drugs or medical devices and have not reached the primary endpoint;
  2. Patients were unable or unwilling to participate in the study;
  3. Patients were judged by the investigator to be ineligible for participation in the trial.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of diameter
Time Frame: 3 months, 6 months,12 months after operation
The changes of true lumen, false lumen and total aortic diameter before and after surgery in the level of pulmonary artery bifurcation/left atrial (L1), the distal end of covered stent (L2), superior mesenteric artery (L3) and abdominal aortic bifurcation (L4) were recorded.
3 months, 6 months,12 months after operation
Changes of cross-sectional area
Time Frame: 3 months, 6 months,12 months after operation
The changes of true lumen, false lumen and total aortic cross-sectional area before and after surgery in the level of pulmonary artery bifurcation/left atrial (L1), the distal end of covered stent (L2), superior mesenteric artery (L3) and abdominal aortic bifurcation (L4) were recorded.
3 months, 6 months,12 months after operation
Volumetric change
Time Frame: 3 months, 6 months,12 months after operation
The volumes of the true lumen and false lumen of the aorta before and after surgery were measured from the covered stent placement segment, the proximal end of the bare stent to the level of celiac trunk, from the level of celiac trunk to the level of low kidney, and from the level of low kidney to the abdominal aorta bifurcation.
3 months, 6 months,12 months after operation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Splanchnic arteries perfusion
Time Frame: 3 months, 6 months,12 months after operation
The change rate of postoperative true lumen diameter of branch artery = (postoperative true lumen diameter - preoperative true lumen diameter)/preoperative true lumen diameter ×100%
3 months, 6 months,12 months after operation
Incidence of distal new entry
Time Frame: 3 months, 6 months,12 months after operation
The number of visceral artery segment tears and infrarenal abdominal aorta segment tears were evaluated.
3 months, 6 months,12 months after operation
Tortuosity of the descending thoracic aorta
Time Frame: 3 months, 6 months,12 months after operation
Tortuosity of the descending thoracic aorta = the length of left subclavian artery to descending aorta of coeliac trunk along the center lumen line/the outer curvature length of left subclavian artery to coeliac trunk
3 months, 6 months,12 months after operation
Immediate technical success
Time Frame: Immediate during surgery
Immediate technical success was defined as the stent was successfully delivered to the intended site and released.
Immediate during surgery
Incidence of type I and III endoleak
Time Frame: Immediate during surgery,3 months, 6 months,12 months after operation
Immediate during surgery,3 months, 6 months,12 months after operation
Major adverse events occurring within 30 days after surgery
Time Frame: within 30 days after operation
Refers to all-cause mortality, myocardial infarction, ischemic stroke or respiratory failure occurring within 30 days after surgery. More specifically, myocardial infarction refers to a drastic reduction or complete interruption of the coronary blood supply due to coronary artery disease, resulting in severe and prolonged acute ischemia of the corresponding myocardium, leading to necrosis of cardiomyocytes. Ischemic stroke refers to the end result of necrosis of brain tissue caused by narrowing or occlusion of the arteries supplying blood to the brain or insufficient blood supply to the brain. Respiratory failure is defined as a state resulting in significantly prolonged intubation, tracheotomy, deterioration of lung function, or other fatal outcomes.
within 30 days after operation
Incidence of severe adverse events
Time Frame: 3 months, 6 months,12 months after operation
Refers to an event that occurs during the clinical trial that results in mortality or serious deterioration in patient health, including a fatal illness or injury, a permanent defect in body structure or body function, or an event that requires medical or surgical intervention to avoid one or more permanent defects in body structure or body function.
3 months, 6 months,12 months after operation
