Purpose:
To describe transvenous embolization in four patients with indirect dural carotid cavernous fistulas (CCFs) via the inferior petrosal sinus (IPS) or superior ophthalmic vein (SOV), and their clinical outcomes.
Methods:
The CCF approach was performed after retrograde venous catheterization from the femoral vein to the cavernous sinus via the IPS (n=1) or SOV (n=3). SOV catheterization was possible without surgical intervention. All patients presented initially with typical clinical signs of CCF. Patients treated via the SOV presented with thrombosis of the IPS.
Results:
Catheterization and embolization were successful in all patients, with complete angiographic occlusion of the fistula. No early or late complications occurred. All patients presented with favorable clinical outcomes and complete recovery of ocular symptoms.
Conclusion:
Retrograde transvenous embolization of CCF via the IPS, or SOV if the IPS is thrombosed, is a safe procedure with a good clinical outcome.
