Transarterial embolization of sinus dural arteriovenous fistula using non-adhesive liquid embolic material

Objective: The objective is to report our experience of transarterial embolization of sinus dural arteriovenous fistula (DAVF) using non-adhesive liquid embolic material.Materials and methods: In 3 cases of Borden type II sinus DAVFs, a Copernic balloon was used to protect sagittal sinus in one patient, palliative Onyx embolization was performed to protect transverse sinus in one patient and EVAL/DMSO/ethanol mixture (EVAL, SUCCESS, Shandong, China) was used in the last patient.Results: Two Borden type II DAVFs were changed into type I DAVF and one was cured. The dural sinus was patent after successful Onyx embolization in 3 cases resulting in well patient recovery. There were no treatment-related events.Conclusion: Transarterial embolization of sinus DAVF using non-adhesive liquid embolic material could be effective and safe with sinus protection techniques.
