Objective:
We report a case of dural arteriovenous fistula (dAVF) at the cavernous sinus treated by direct puncture of the superior ophthalmic vein (SOV) using an electromagnetic navigation system.
Case Presentation:
The case involved a 70-year-old male patient who presented with mild chemosis, proptosis, and abducens palsy of the right eye. In this case, we used an electromagnetic navigation system for direct puncture of the SOV. Angiographic obliteration of the fistula was confirmed and the visual symptoms recovered well after surgery. There were no complications associated with direct puncture of the SOV using the electromagnetic navigation system.
Conclusion:
Direct puncture of the SOV to obliterate a dAVF is a possible alternative choice of treatment when the usual transvenous access route fails. To reduce the risk of complications, an electromagnetic navigation system is useful.
