To explore the effect and prognosis of endovascular interventional therapy in high-risk patients with aortic arch dissection and aneurysm
The WeFlow-Tribranch Aortic Arch Stent Graft System first in man study is a prospective, multi-center, single arm trial, which will enroll a total of 20 patients. The goal of this study is to evaluate the safety and efficacy of WeFlow-Tribranch Aortic Arch Stent Graft System in the treatment of patients with aortic arch dissection and aneurysm.
205 studies on the registry are indexed under Aortic Dissection; 73 are open to participants now.
This study's planned enrollment of 20 is below the median of 114 across 86 interventional studies indexed under Aortic Dissection.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Device: WeFlow-Tribranch Aortic Arch Stent Graft System
Endovascular treament in patients with aortic arch dissection and aneurysm by WeFlow-Tribranch Aortic Arch Stent Graft System
All-cause mortality and major stroke within 12 months after surgery.
All-cause mortality includes cardiac mortality, non-cardiac mortality and mortality from unknown causes. Severe stroke is defined as a modified Rankin score (mRS) ≥ 2 at 90 days following stroke onset
Time frame: 12 months post-intervention
Aortic-related mortality within 12 months post operation.
Refers to mortality caused by a ruptured aortic dissection/aneurysm or endovascular interventional treatment.
Time frame: within 12 months post operation
Aortic remodeling results.
Compare the results of CTA before operation and on the 30th day, 6th month and 12th month after operation, the expansion of the true lumen and the thrombosis of the false lumen at the coverage of the aortic dissection vascular stent to determine whether the blood vessel is successfully remodeled,or CTA reexamination 12 months after operation showed that the maximum diameter of Aortic aneurysm increased by ≤ 5 mm compared with that before operation.
Time frame: 1 month, 6 months and 12 months post-intervention
Major adverse events occurring within 30 days after surgery.
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.
Time frame: within 30 days after surgery
Incidence of severe adverse events.
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.
Time frame: within 12 months post-intervention
