Trial summary

The cerebral arteriovenous malformations correspond to the formation of an entanglement of morphologically abnormal vessels called nidus, which shunt the blood circulation directly from the arterial circulation to the venous circulation. Read more about this study

About this study

Official title: Biology of Cerebral Arteriovenous Malformations : Study of the Link Between Blood Biomarkers and the Haemorrhagic Prognosis of Cerebral Arteriovenous Malformations

The cerebral arteriovenous malformations correspond to the formation of an entanglement of morphologically abnormal vessels called nidus, which shunt the blood circulation directly from the arterial circulation to the venous circulation.

The cerebral arteriovenous malformations are an important cause of hemorrhagic stroke.

The hypothesis is that cerebral haemorrhage associated with a cerebral arteriovenous malformations would come from peri-nidal micro-vessels, in connection with infiltration of leucocytes and / or defective maintenance of microvascular integrity by platelets.

Medical subject headings
Intracranial Arteriovenous Malformations, Rupture

What is being measured

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

  1. Associaton between dosage of endothelial marker and the arteriovenous malformation pronostic

    associaton between dosage of endothelial marker in blood samples and correlation with clinical outcome

    Measured: 6 months

  2. Associaton between dosage of platelet and the arteriovenous malformation pronostic

    Dosage of platelet in blood samples and correlation with clinical outcome

    Measured: 6 months

  3. Associaton between dosage of neutrophilic and the arteriovenous malformation pronostic

    Dosage of neutrophilic in blood samples and correlation with clinical outcome

    Measured: 6 months

  4. Associaton between neo-angiogenesis activation markers and the arteriovenous malformation pronostic

    Dosage neo-angiogenesis activation markers in blood samples and correlation with clinical outcome

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Cerebral Arteriovenous Malformations and Ruptured or Unruptured Cerebral Arteriovenous Malformations, run by Fondation Ophtalmologique Adolphe de Rothschild 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 6 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 25 Jun 2025. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Amélie Yavchitz (01 48 63 64 54 ext. +33, ayavchitz@for.paris), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Associaton between dosage of endothelial marker and the arteriovenous malformation pronostic (time frame: 6 months). The study lists 4 primary outcomes in all. 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 25 Jun 2025.
