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.",[214],"Intracranial Dural Arteriovenous Fistula",[216,217,218,219],"intracranial dural arteriovenous fistula","fistula","malforamtion","outcome","2026-06-02",{"date":222,"type":223},"2026-06-04","ACTUAL",{"date":225,"type":209},"2026-05-18",{"date":227,"type":209},"2030-02-28",{"name":5,"class":6},1]
