Dural AVF Embolization Using Proximal Balloon Catheter Occlusion Technique
A 48-year-old male presented with recurrent headaches associated with blurring of vision. Clinical examination was unremarkable. MRI of the brain revealed dilated vessels in sulcal spaces of right temporoparietal region. No evidence of parenchymal changes was seen. Cerebral DSA was performed via transfemoral route which revealed dural AVF in right temporal region with feeders from right middle meningeal and occipital arteries. Drainage was through dilated cortical veins into the superior sagittal and transverse sinuses. Cortical venous drainage carries significant risk of bleeding, and therefore it was decided to treat the malformation by embolization.
