Abstract:
Objective To investigate the technique of transarterial embolization of dural carotidcavernous fistulas(DCCFs)with low concentration(14%-25%)of n-butyl-cyanoacrylate(NBCA)and determine its value.Methods Eight patients with DCCFs were treated by transarterial embolization with low concentration of NBCA using a wedged microcatheter.Of the 8 patients,5 had unsuccessful transvenous embolization and 3 could not be treated with transvenous embolization.Results Transarterial embolization with low concentration of NBCA using a wedged microcatheter resulted in complete obliteration of the affected cavernous sinus and related shunts in 5 patients,no residual arteriovenous shunt was demonstrated on postembolization angiography.On clinical and angiographic follow-up 6-12 months later,complete resolution of clinical symptoms was observed in all 5 patients and there were no recurrent or residual DCCFs found.Partial obliteration of the involved cavernous sinus and the related shunt was achieved in the remaining 3 patients on immediate post-procedure angiography,but the volume of shunt diminished significantly.On clinical and angiographic follow-up 3 months later,in 2 patients,clinical symptoms were improved and the arteriovenous shunts were diminished;in the third patient,clinical symptom resolved and the shunt was obliterated.There were no major complications except for the transient worsening of ocular symptoms due to Ⅵ cranial nerve palsy in 1 patient.Conclusions Transarterial embolization of DCCFs with low concentration of NBCA using a wedged microcatheter was a safe and effective treatment method.It is an optimal alternative for the patients with DCCFs in which transvenous route was unsuccessful,or impossible.
