Advantage of Balloon Guide Catheter During Endovascular Treatment of Direct Carotid-Cavernous Sinus Fistula: Technical Note and Report of 2 Cases

초록

BACKGROUND: As previous studies reported, the ballon guide catheter is useful for identifying the fistula point during diagnosis of direct carotid-cavernous sinus fistula (d-CCF). We demonstrate an additional advantage of the balloon guide catheter during intraarterial endovascular treatment of d-CCF. METHODS: Two cases of d-CCF are presented in this -port. A balloon guide catheter is used to help achieve successful coil embolization of the fistula in both cases. RESULTS: Microcatheter positioning into the fistulous point can be easier after balloon inflation. Balloon inflation can help with coil deployment. CONCLUSIONS: Using a balloon guiding catheter can reduce internal carotid artery flow near the fistula point at the cavernous segment of the internal carotid artery. As a result, better identification of the fistula point can be made, which allows easier placement of the microcatheter into the fistula point and more stable coil deployment.
