Multicenter Registry Study of Patients With Intracranial Dural Arteriovenous Fistulas in China (DREAM)
18. maj 2026 opdateret af: Xuanwu Hospital, Beijing
Dural Arteriovenous Fistulas Registry, Evaluation, and Management Study in China (DREAM)
This multicenter registry study aims to clarify the incidence trends of intracranial dural arteriovenous fistulas (IDAVF) and spinal dural arteriovenous fistulas (SDAVF) in China, evaluate current treatment patterns, and establish a nationwide multicenter retrospective and prospective database.
The study is designed as a multicenter retrospective and prospective observational study involving more than 60 core hospitals across seven major geographic regions of China.
The retrospective phase will include patients diagnosed between February 28, 2015 and February 28, 2025, while the prospective phase will enroll patients from March 1, 2025 to March 1, 2030.
Eligible participants are patients diagnosed with IDAVF or SDAVF by digital subtraction angiography (DSA).
The study will analyze disease incidence and temporal trends, collect baseline demographic and clinical characteristics, and evaluate treatment outcomes including obliteration rate, recurrence rate, and clinical prognosis.
The crude incidence rate per 100,000 person-years during the study period will also be calculated based on Chinese census population data.
The primary endpoint is the improvement rate in modified Rankin Scale (mRS) score at 6 months after treatment.
Secondary endpoints include obliteration and recurrence rates on imaging follow-up at 6 months and improvement in mRS score at 12 months after treatment.
Statistical analyses will be performed using SAS 9.4 software, including descriptive analyses as well as univariate and multivariate regression analyses to identify factors associated with clinical outcomes and prognosis.

Studiebefolkning
The study population consists of patients diagnosed with intracranial dural arteriovenous fistulas (IDAVF) or spinal dural arteriovenous fistulas (SDAVF) at more than 60 participating centers across seven geographic regions of China.
Both retrospective and prospective cohorts will be included.
Eligible patients will be identified based on digital subtraction angiography (DSA)-confirmed diagnosis and available clinical and imaging data.

- Patients treated or evaluated at participating centers during the study period
- Availability of complete clinical and imaging records, including baseline information, treatment records, and DSA images
- For the prospective cohort, written informed consent signed by the patient or legal representative
Exclusion Criteria:
