Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 100 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age ≥ 18 years.
  • Non-traumatic intracranial hemorrhage (ruptured aneurysm, AVM, or per-procedural complication etc)
  • Ruptured aneurysm, AVM, intracranial arterial perforation or any bleeding lesion secured with surgical clipping or endovascular intervention.
  • No contra-indication to both CTP and MRI imaging
  • Subject or legal representative is able and willing to give informed consent.
  • Refractory of intracranial arterial vasospastic stenosis requiring an endovascular angioplasty with a severe stenosis defined on CTA or DSA; and/or a significant hypoperfusion defined according to the mismatch profile in stroke or a MTT>6 seconds. The volume of critically hypoperfused tissue will be based on a time to maximum of the tissue residue function (Tmax) threshold of >6 sec using the Rapid (or equivalent) software.

Who cannot join

  • Angioplasty by one of the two methods considered as impossible or too risky by the neurointerventionist
  • Inability to obtain consent from patient or patients relatives
  • Pregnant women
  • Less than 18 years of age
  • Need to use any other device
  • Vertebro-basilar arteries will not be randomized because of the difficulty to assess the perfusion volume in this territory, but will be treated if necessary according to our local protocol.

About this study

Official title: Comparison of Two Validated Endovascular Strategies for Refractory Vasospastic Stenosis After Non-traumatic Intracranial Haemorrhage Leading to Severe Brain Hypoperfusion: Chemical Versus Chemical and Mechanical Angioplasty

This is a monocentric randomized prospective trial comparing 2 different endovascular strategies of intracranial arterial angioplasty in case of refractory intracranial arterial vasospastic stenosis :

  • chemical angioplasty
  • chemical and mechanical angioplasty
Read the detailed description

Compare in a randomized prospective trial 2 approved treatments of refractory intracranial arterial vasospastic stenosis, chemical angioplasty versus chemical and mechanical angioplasty, using devices already used in clinical practice and CE marked: chemical angioplasty using Nimotop versus chemical and mechanical angioplasty with balloon or adjustable remodeling mesh on brain perfusion evaluated by brain computed tomography (CT) Perfusion

Nowadays, the choice between chemical or chemical and mechanical angioplasty depends on the neurointerventionist for each procedure, no difference in efficiency or safety has been proved and no solid scientific data helps the physician in choosing the correct treatment for each patient.

Being tested
Chemical and Mechanical Angioplasty for Refractory Intracranial Arterial Vasospastic Stenosis

What is being measured

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

  1. Change in brain hypoperfusion

    Brain hypoperfusion in arterial territories assessed by the delays on perfusion Time to drain (seconds) on CT and/or MR perfusion

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

Secondary outcomes (11)
  1. Change in vessel size

    Change in the vessel size measured on digital subtraction angiography (DSA) and computed tomography angiogram (CTA) in millimeters

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

  2. Time to next endovascular intervention for vasospastic stenosis

    Delay between two procedures for the same indication

    Measured: Number of days after the endovascular procedure until the next procedure in days, up to 4 weeks

  3. modified Rankin Scale at 3 months

    clinical evolutionclinical evolution (mRS between 0 and 6, a higher score means a worse outcome)

    Measured: 3 months after Intracranial Hemorrhage

  4. Change in Transcranial Doppler

    Change in intracranial vasospasm assessed by the targeted vessel velocity in meters per second

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

  5. change in Brain Hypoperfusion 2

    Reduction in brain hypoperfusion assessed by the volumes on different perfusion parameters time to peak (in seconds) on CT and/or MR perfusion

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

  6. change in Glasgow coma scale

    Glasgow coma scale (GCS between 3 and 15, a higher score means a better outcome)

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

  7. change in National Institutes of Health Stroke Scale score

    National Institutes of Health Stroke Scale (NIHSS between 0 and 42, a higher score means a worse outcome)

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

  8. Change in the monitoring of tissue oxygen pressure (PtiO2)

    Monitoring of tissue oxygen pressure (PtiO2)

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

  9. Number of new ischemic lesions

    Number of new ischemic lesions on non-contrast computed tomography (CT) scan

    Measured: Change between day 0, 5, 9, 21 after Intracranial Hemorrhage

  10. Change in brain hypoperfusion 3

    Brain hypoperfusion in arterial territories assessed by the delays on perfusion parameters TMax maps in seconds on CT and/or MR perfusion

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

  11. Change in brain hypoperfusion 4

    Brain hypoperfusion in arterial territories assessed by the delays on perfusion parameters Mean transit time on CT and/or MR perfusion in seconds

    Measured: Change between day 0 and day 1 after the endovascular procedure and randomization

Questions about this trial

What is this clinical trial studying?

A study testing Chemical and Mechanical Angioplasty for Refractory Intracranial Arterial Vasospastic Stenosis in people with Aneurysmal Subarachnoid Hemorrhage and Vasospasm, Intracranial, run by Erasme University Hospital at 1 site in Belgium.

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 6 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 21 Feb 2024. 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 Belgium. 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?

Change in brain hypoperfusion (time frame: Change between day 0 and day 1 after the endovascular procedure and randomization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05268445, which also lists 1 linked publication.

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 Feb 2024.
