Brief Summary:
The primary objective of this study is to demonstrate the safety and efficacy of the PHIL® liquid in endovascular treatment of dural arteriovenous fistula.

Condition or disease
Dural Arteriovenous Fistula

Detailed Description:

This is an European multi-center observational study. Treatments and follow-up visits will be done as per standard of care.

The objective of this study is to evaluate the efficacy and safety of the PHIL® device in the treatment of intracranial dural ArterioVenous Fistula (dAVF). The PHIL® device, a non-adhesive liquid embolic agent, has been CE marked since July 2014. It is intended for use in the embolization of lesions in the peripheral and neurovasculature, including arteriovenous malformations and hypervascular tumors.

All patients with an intracranial dAVF that has not been previously treated and will be treated by embolization with PHIL® are eligible for this study. A maximum of 60 patients will be enrolled in this study in 16 European Institutions.

The expected approximate study duration is 24 months.

Primary Outcome Measures :
  1. Number of adverse events and assessment of neurological status at 1 month after each embolization [ Time Frame: 1 month ]
    Neurological assessment by mRS

  2. Assessment of cure rate and of clinical course of the patient (stable /improvement /deteriorated) [ Time Frame: 3-6 months after last embolization ]
    Cure rate assessment by Angiography

Secondary Outcome Measures :
  1. Number of adverse events and assessment of neurological status [ Time Frame: 3-6 months after last embolization ]
    Neurological assessment by mRS

  2. Improvement in the quality of life of the patient and changes in patients symptoms [ Time Frame: 3-6 months after last embolization ]
    Assessed by Quality of Life Questionnaire EQ 5D

  3. Patient is at least 18 years of age.

Exclusion Criteria:

  1. Patient has multiple dAVFs to be treated.
  2. Patient participates in a study evaluating another medical device, procedure, or medication during the course of dAVF treatment and follow-up per the study protocol.
  3. Patient does not give consent to the collection and processing of data required for centralized monitoring
