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 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: patients that suffered from intracerebral hemorrhage (ICH) due to a ruptured artery-venous malformation (AVM)

About this study

The primary objective of this multicenter study is to validate the AVICH score in terms of patient outcome prediction in AVM patients with associated ICH.

Secondary objectives are the impact of pretreatment of the AVICH score. Patients outcome is measured using the modified Rankin Scale (mRS) and are grouped in favorable (mRS score, 0-2) and unfavourable (mRS score, 3-6) outcome at last follow-up (LFU). The following parameters, which are part of the AVICH score, will be compared between the 2 groups: ICH score including age, Glasgow Coma Scale (GCS) score, haemorrhage volume, presence of intraventricular hemorrhage (IVH), and localization of the ICH. Spetzler-Martin grade including AVM size, eloquent location, and venous drainage, as well as the Lawton-Young grade, including age, presence of ruptured AVM, and the nidus structure. In addition pre-/postruptured treatment modalities, including embolization, radiotherapy, surgery or no treatment will be analysed. Outcome (mRS) at 3 months, at 1 year, and at LFU will be compared.

Read the detailed description

Intracerebral hemorrhage (ICH) is the most common life threatening presentation of brain arteriovenous malformations (AVMs). Several AVM grading systems are available for presurgical risk assessment to help selecting patients for surgery. The most widely accepted and classic grading system is the Spetzler-Martin grading system; however, the recently introduced and externally validated supplemented Spetzler-Martin system seems to have an even better predictive accuracy. The pathophysiology of AVM-related ICH and spontaneous ICH is completely different. It is well known that clinical outcome in patients suffering spontaneous ICH is worse compared with patient outcome after AVM-related ICH. For spontaneous ICH, not related to AVM, several scoring systems exist to predict patient outcome. The most commonly used system is the ICH score. The available ICH scoring systems may not predict outcome in patients with hemorrhage caused by AVM rupture with the highest accuracy possible. Therefore, we examined a new scoring system called the AVM-related ICH score (AVICH score), which predicts patient outcome in the acute setting of AVM rupture. This scoring system is a special adaptation of the supplemented Spetzler-Martin grading system designed for patients presenting with hemorrhage, which includes additional clinical and radiographic information. Based on the area under the receiver operating characteristics curve (AUROC) analysis in this single center analysis, the AVICH score predicts outcome of patients with ruptured AVM and associated ICH better than the ICH score, the Spetzler-Martin, or the supplemented Spetzler-Martin grading system. An external validation is needed before the AVICH score is tested in a prospective multicenter cohort.

The primary objective of this multicenter study is to validate the AVICH score in terms of patient outcome prediction in AVM patients with associated ICH.

Secondary objectives are the impact of pretreatment of the AVICH score. Patients outcome is measured using the modified Rankin Scale (mRS) and are grouped in favorable (mRS score, 0-2) and unfavourable (mRS score, 3-6) outcome at last follow-up (LFU). The following parameters, which are part of the AVICH score, will be compared between the 2 groups: ICH score including age, Glasgow Coma Scale (GCS) score, haemorrhage volume, presence of intraventricular hemorrhage (IVH), and localization of the ICH. Spetzler-Martin grade including AVM size, eloquent location, and venous drainage, as well as the Lawton-Young grade, including age, presence of ruptured AVM, and the nidus structure. In addition pre-/postruptured treatment modalities, including embolization, radiotherapy, surgery or no treatment will be analysed. Outcome (mRS) at 3 months, at 1 year, and at LFU will be compared.

Key inclusion criteria:

  • All patients with ICH associated AVMs and a modified Rankin Scale <2 (so 0-1) before hemorrhage
  • Pretreatment (embolization, radiosurgery, surgery) before ICH is not an exclusion criteria.

Questions about this trial

What is this clinical trial studying?

An observational study of Intracerebral Hemorrhage and Arterio-venous Malformation, run by University of Zurich.

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 2 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: status not confirmed, as of the sponsor's last update on 30 Sep 2016. 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?

Results are not available in the source record.

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?

neurological long-term outcome (modified Ranking Scale, mRS) (time frame: up to 3 years at last follow-up). 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 NCT02920645, which also lists 2 linked publications.

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 30 Sep 2016; AzTrials last refreshed its copy on 30 Oct 2026.
