Abstract：Objective To investigate the application value of 3D venous fusion technology in determining whether the drainage vein of dural arteriovenous fistula(DAVF)associated with cortical venous drainage simultaneously has normal cerebral venous reflux.Methods The clinical data of 6 patients with DAVF associated with cortical venous drainage who admitted to our hospital from September 2021 to March 2023 were retrospectively analyzed.The"3D dual vessel fusion technology"was used in the post-processing workstation to perform 3D fusion of fistula drainage veins and normal cerebral veins using DSA data,marked with white and blue to distinguish them,and the two type vessels could be clearly observed by the fusion images to determine if they had a common path,thereby determining whether the drainage vein had normal cerebral venous reflux.Results Good 3D fusion images were obtained in all 6 cases,and the dual vessel fusion images clearly showed that the drainage vein(white)overlapped with the normal cerebral venous reflex(blue)and had a common path,indicating that it had normal cerebral venous reflux.All 6 patients had curative embolization,and postoperative angiography showed that the normal reflux was preserved.No intracranial hemorrhage,or cerebral infarction occurred after surgery,and the symptoms were relieved or disappeared.The DSA follow-up 3～6 months after surgery did not show recurrence of DAVF.Conclusions The 3D venous fusion technology can help determine whether the drainage vein of DAVF associted with cortical venous drainage also has normal cerebral venous reflux.Protecting these veins during surgery can reduce surgical complications.
