Objective: Transarterial embolization (TAE) of the cavernous sinus (CS) via a fistula formed in the internal carotid artery (ICA) is the standard for carotid-cavernous fistulas (CCFs). Depending on the fistula, an adjunctive technique using a balloon or stent is effective. We report a case in which the balloon-assisted technique using the super-compliant balloon catheter “Super-Masamune” was effective.
Case Presentation: A 44-year-old woman who sustained head trauma from a traffic accident 1 month prior presented with diplopia, conjunctival chemosis, and proptosis of the left eye. Digital subtraction angiography (DSA) revealed a left CCF with a reflex to the left superior ophthalmic vein (SOV). During TAE with the Super-Masamune assistance, we tightly embolized around the fistula using a small volume of coils and the CCF was obliterated.
Conclusion: The balloon of the Super-Masamune is made of a styrene-based elastomer, which has excellent compliance. Therefore, it is possible to reduce the volume of coils because the balloon is in close contact with the ICA or fistula. This may reduce the incidence of postoperative cranial nerve palsy and cost of treatment materials.
