Abstract:

Objective

To discuss the safety and efficacy of balloon-assisted sinus coiling plus Onxy embolization technique in the treatment of carotid cavernous fistula (CCF).

Methods

Nineteen cases of CCF admitted into the Department of Neurosurgery of Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital from January 2018 to June 2020, are retrospectively studied. Balloon-assisted sinus coiling plus Onxy embolization technique was conducted in all cases. Among them, 11 cases with open inferior petrosal sinus were treated with embolization via inferior petrosal sinus vein, and 8 cases were treated with transcatheter arterial embolization via internal carotid artery fistula.

Results

Immediate obliteration of the fistula was achieved in all cases, without additional neurological dysfunction. Symptoms resulting from ophthalmic vein hypertension relieved evidently immediately after the surgery and gradually disappeared within 1-2 weeks. The symptoms of extraocular muscle paralysis were relieved relatively slowly.

Conclusion

Through imaging editing technique after 3D-image reconstruction, the location of fistula can be accurately determined, making the coil and Onxy glue as close to the fistula as possible, so as to reduce the cost, improve the safety and efficacy of CCF treatment.

Key words: Carotid cavernous fistula, Embolization, Transvenous pathway, Transarterial pathway
