Abstract:
Objective To explore the curative effect of embolism of cavernous sinus with Onyx and coils on cavernous sinus dural arteriovenous fistulas (csDAVFs) and to sum up the experiences.Methods Retrospective analysis of clinical data and radiographic records of 25 patients with csDAVFs who had received embolisation of cavernous sinus using Onyx or in combination with coils through inferior petrosal sinus between August 2008 and February 2013 was performed;all patients were diagnosed by conventional cerebral angiography and received ophthalmological examination before operation.Twenty-two patients used coils and Onyx,three patients used Onyx only.Results Twenty-five embolization sessions were conducted.The mean number of coils was 2.55±0.91 and the mean volume was 32.15±16.03 mm3per patient;the mean volume of Onyx was 2.57±0.86 mL per patient.Three patients (12.0％) who used only Onyx achieved subtotal occlusion and other 22 patients (88.0％) were completely occluded in the immediate angiography.All patients (100％) achieved complete occlusion in the follow-up angiography.Seven patients (28.0％) demonstrated no symptoms at discharge time and 18 patients (72.0％) demonstrated symptoms improvement.All patients remained asymptomatic in the subsequent follow-up periods.Six patients (24.0％) occurred complications and all the complications were cured after proper treatment.Conclusion Effective use of Onyx and coils is the key to cure cavernous sinus dural arteriovenous fistulas and reduce the complications.
