About this study

Prospective, single-arm, multi-center registry study A total of 50 subjects with Type B aortic dissection who meet all inclusion and exclusion criteria will be included.

Patients will be treated with TEVAR using conformable TAG endograft (Gore). Patients will be followed clinically for 12 months after the procedure. CT will be performed at 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Major adverse event

    A composite of all-cause death, re-intervention, and aortic dilation > 5 mm in maximal aortic diameter

    Measured: 12 months

Secondary outcomes (2)
  1. Aortic remodeling

    Change in maximal aorta, true lumen, and false lumen dimensions

    Measured: 12 months

  2. Aorta-related complications

    composite events of aortic rupture, stroke, spinal chord ischemia, retrograde dissection, endoleaks, aortic dilation > 5mm in diameter

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Type B Aortic Dissection, run by Yonsei University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 21 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major adverse event (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jun 2018.
