Interventional Embolization of Unilateral Cavernous Sinus With ONXY Glue Combined With Coils for the Treatment of Bilateral Dural Arteriovenous Fistula.

PURPOSE: To summarize the clinical experience of unilateral sponge sinus embolization of cavernous sinus dural arteriovenous fistula (CS DAVF) via jugular vein access with ONXY gel and spring coil intervention.

METHODS: The authors retrospectively analyzed the clinical data of 3 patients who were treated with unilateral cavernous sinus embolization for bilateral cavernous sinus dural arteriovenous fistula (CS DAVF) from October 2020 to May 2022 in our department by using transjugular vein access spring coil + ONXY gel interventional embolization.

RESULTS: Immediate postoperative angiography suggested that the cavernous sinus fistula was completely embolized in all 3 patients, and cerebral angiography was carried out from 6 to 12 months after the operation and assessed using the Class grading method, and there was no recurrence in any of the 3 patients.

CONCLUSIONS: Transvenous access ONXY adhesive combined with spring coil interventional embolization of unilateral cavernous sinus to cure bilateral cavernous sinus dural arteriovenous fistula is feasible, which can avoid the excessive use of spring coils and ONXY adhesive, and it is the key to the effective cure of DAVF in cavernous sinus area and to reduce the complication.
