Trial summary

Cervical artery dissection (CAD) accounts for about 2% of all strokes, and is a major cause of stroke in young people (about 15%). Many cases of CAD during pregnancy and puerperium have been described, suggesting that pregnancy and puerperium may be potential risk factors for CAD. Read more about this study

About this study

Official title: A Prospective Study to Evaluate the Risk of Recurrence of Cervical Artery Dissection During Subsequent Pregnancies

Cervical artery dissection (CAD) accounts for about 2% of all strokes, and is a major cause of stroke in young people (about 15%). Many cases of CAD during pregnancy and puerperium have been described, suggesting that pregnancy and puerperium may be potential risk factors for CAD. The purpose of this study is to determine whether pregnancy and puerperium are also recurrence risk factors for CAD.

Read the detailed description

In this study, all women of childbearing age who had had a CAD between 2005 and 2017 are selected. Women are identified using the ICD10 diagnostic coding system. In addition, a text search with key words ("cervical or carotid or vertebral dissection") has been created in a data warehouse of the University Hospital of Nantes.

To determine the recurrence of CAD during pregnancy and puerperium, the participating women will be asked to answer to a questionnaire, by phone or mail. The questionnaire will be conducted by the same investigator, an experienced neurologist. Information about recurrence of CAD, number of pregnancies before and after the event will be recorded, as well as, the site of obstetrical monitoring, way of delivery, and management of antithrombotics, in case of further pregnancy. In case of no further pregnancy after the dissection, the reason will be explored.

What is being measured

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

  1. Recurrence of CAD during pregnancy, childbirth or puerperium

    This primary study endpoint will be evaluated by a questionnaire asked directly to participating women.

    Measured: Day 0

Secondary outcomes (3)
  1. To determine the absolute risk of recurrence of CAD in this population.

    This secondary endpoint will be evaluated by a questionnaire asked directly to participating women.

    Measured: Day 0

  2. To assess obstetrical monitoring, way of delivery, and management of antithrombotics during further pregnancy.

    This secondary endpoint will be evaluated by a questionnaire asked directly to participating women.

    Measured: Day 0

  3. To study the reasons of absence of pregnancy after a history of CAD

    This secondary endpoint will be evaluated by a questionnaire asked directly to participating women.

    Measured: Day 0

Questions about this trial

What is this clinical trial studying?

An observational study of Cervical Artery Dissection, run by Nantes University Hospital at 1 site in France.

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 4 inclusion and 4 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: finished, as of the sponsor's last update on 2 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Recurrence of CAD during pregnancy, childbirth or puerperium (time frame: Day 0). 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 2 Dec 2020.
