Summary

The goal of the clinical trial is to describe perfusion and metabolic alterations in different brain regions before and six months after surgical treatment of arteriovenous malformations in adult patients with unruptured arteriovenous malformations.

Conditions

  • Unruptured Brain Arteriovenous Malformation

Interventions

RADIATION

18F-FDG PET imaging

For the 18F-FDG (fluorodeoxyglucose labelled with fluorine-18) PET scan, a dynamic protocol with the radiopharmaceutical injected directly under the scanner. The dose injected will be the same as that used in routine clinical practice, i.e. calculated based on the patient's weight. The patient must fast for 6 hours prior to the examination. The total duration of the dynamic PET scan is estimated at approximately 1 hour 30 minutes.

OTHER

Neuropsychological Assessment

For the neuropsychological assessment, a series of standardised tests, validated for the assessment of cognitive functions, will be administered. This assessment will be carried out by neuropsychologists trained in the use of these tests and who administer them as part of their routine practice, or by a trained physiatrist specialising in disorders of the central nervous system. The neuropsychological assessment is expected to take 2 to 3 hours per visit for the patient.
