MI-összefoglaló

A vizsgálat saját részvételi feltételeiből. Gép olvasta ki az oldalon álló regiszterszövegből, ezért tévedhet. Hogy ki vehet részt, azt a lenti regiszterszöveg és a vizsgálat csapata dönti el.

The trial is looking for adults with an abdominal aortic aneurysm (a bulge in the main belly artery) below the kidneys. They either have a burst aneurysm, or an intact one being repaired by open surgery or a catheter procedure. No experimental treatment is given.

Életkor
18 years or older
Nem
All sexes
A betegség stádiuma
Infrarenal abdominal aortic aneurysm (below the kidney arteries). It is either ruptured (burst), with or without repair afterwards, or intact and being repaired by open surgery or endovascular repair.
Korábbi kezelés
A CT scan must have been taken before any surgery or endovascular procedure on the aneurysm.
Biomarker vagy leletérték
A CT scan good enough to measure the largest aneurysm width. Height and weight records must also be available.

A részvétel fő kizáró okai

  • Aneurysm not located below the kidney arteries
  • No good-quality CT scan taken before treatment
  • No usable height or weight value
  • Pregnancy at the time of enrolment
  • Refusing to take part or withdrawing consent

Ki vehet részt

  • Age 18 years or older
  • Documented ruptured infrarenal abdominal aortic aneurysm (AAA) with adequate computed tomography (CT) imaging obtained before any surgical or endovascular intervention, regardless of whether repair is subsequently performed; or intact infrarenal AAA undergoing open surgical or endovascular repair
  • Availability of CT imaging of sufficient quality for standardized measurement of maximum aneurysm diameter
  • Availability of height and weight data obtained and documented according to the prespecified anthropometric measurement hierarchy, including the source and date of each measurement
  • Written informed consent from the participant or a legally authorized representative when required and feasible, according to the ethics-approved procedures applicable at each participating center

Ki nem vehet részt

  • Absence of adequate CT imaging obtained before any surgical or endovascular intervention, or imaging of insufficient quality to reliably measure maximum aneurysm diameter
  • Age younger than 18 years
  • Aneurysm not classified as infrarenal
  • Absence of any usable height or weight value from the prespecified anthropometric measurement hierarchy, precluding calculation of the Aortic Size Index (ASI) and Aortic Height Index (AHI)
  • Active pregnancy at the time of enrollment
  • Refusal to participate or withdrawal of informed consent

A vizsgálatról

Mit akar kideríteni a vizsgálat

The goal of this observational study is to learn whether adjusting abdominal aortic aneurysm (AAA) size for body size helps distinguish ruptured from intact aneurysms better than maximum aneurysm diameter alone. The study will evaluate the Aortic Size Index, which adjusts aneurysm diameter for body surface area, and the Aortic Height Index, which adjusts aneurysm diameter for height.

A teljes eredeti leírásKevesebb

The main questions are:

1. Do the Aortic Size Index or Aortic Height Index distinguish ruptured from intact AAAs better than maximum aneurysm diameter alone? 2. What proportion of ruptured AAAs occur below the diameter thresholds of 55 millimeters for men and 50 millimeters for women? 3. Do the findings vary according to sex, participating country, or participating center?

The study will include adults presenting with a ruptured infrarenal AAA and adults with an intact infrarenal AAA undergoing open surgical or endovascular repair. Participants will not receive an experimental treatment. Researchers will use computed tomography scans obtained before surgical or endovascular treatment and available height and weight measurements. No additional computed tomography scans will be required for the study.

Researchers will also collect clinical, operative, and mortality information. Vital status will be recorded during the repair procedure, during the index hospitalization, and at 30-day follow-up. For participants who undergo AAA repair, the 30-day period will begin on the date of repair. For participants who do not undergo repair, it will begin on the date of the index clinical presentation. The 30-day assessment will use institutional medical records or telephone contact when necessary.

A vizsgálat 2 csoportja

  • Ruptured Infrarrenal Abdominal Aortic Aneurysm

    Adults presenting with a documented ruptured infrarenal abdominal aortic aneurysm on pre-intervention CT imaging, regardless of whether surgical or endovascular repair is subsequently performed

  • Intact infrarenal Abdominal Aortic Aneurysm undergoing repair

    Adults with an intact infrarenal abdominal aortic aneurysm undergoing open surgical or endovascular repair, including asymptomatic and symptomatic nonruptured cases.
