E-030 A rare case of subarachnoid hemorrhage caused by ruptured venous varix due to dural arteriovenous fistula at the foramen magnum

Conclusion D-AVFs at the foramen magnum, although extremely rare, should be considered as a possible cause of SAH. Detailed inspection of cerebral angiography is mandatory to prevent misdiagnosis. Onyx embolization can be a feasible treatment option to treat such D-AVF. When the D-AVF is fed by neuromeningeal trunk of APA, precise recognition of anatomical location of the lesion by superselective angiography and precise delivery of embolic materials to the fistulous point are required for successful and safe embolization, because there exist dangerous anastomoses between the APA and carotid and vertebral arteries and it carries a significant risk.
