E-213 The role of 3D segmentation in venous embolization of skull base dural arteriovenous fistulae: a case series

ConclusionMMIS is useful in the preprocedural planning and postprocedural analysis of dAVF treatment, especially in cases involving tortuous vasculature and difficulty localizing the fistulous zone as it combines MRI and angiography in a way that can overcome the traditional spatial and temporal dissociation of draining veins and normal venous structures on catheter angiography alone.Abstract E-213 Table 1Case presentations and outcomes Case Number Age (decade) Gender Presentation Diagnosis Location of fistulous point Draining Veins Outcomes 1 50 F Cerebellar SDH Cognard IV Vermian dAVF Superior vermian vein Superior vermian vein with associate venous varix, which drains into a tributary to the torcula 1.
