Abstract：Objective To investigate the endovascular treatment techniques,clinical characteristics,and embolization outcomes of dural arteriovenous fistula(DAVF)in the falx cerebri region.Methods Clinical data of patients who attended the Department of Neurosurgery of Beijing Tiantan Hospital of Capital Medical University and received endovascular treatment from 2010 to 2022 were retrospectively analyzed.The patients were staged according to Congard staging criteria.and were selected for transarterial embolization or combined arteriovenous embolization according to their drainage pattern and lesion location.All patients received regular outpatient and imaging follow-up post-operation to determine the efficacy of endovascular embolization.Results A total of 6 patients were treated with endovascular embolization.Two patients were examined for DAVF due to vertigo,two patients were admitted due to sudden intracranial hemorrhage and two patients were admitted due to DAVF detected on routine physical examination.In the choice of embolization route,transarterial embolization was used in 5 patients and combined transarterial and venous embolization was used in 1 patient.All patients were embolized with a liquid embolization system(Onyx-18).Five patients were embolized primarily via the middle meningeal artery and one patient was embolized primarily via the anterior cerebral artery.Final angiography showed complete occlusion of the DAVF(6/6).Neither intraoperative nor postoperative complications were observed with this treatment modality.Conclusion Endovascular treatment of DAVF in the falx cerebri region is feasible,and transmural middle meningeal artery embolization is the most common treatment modality.
