title: [A case of direct carotid cavernous fistula, whom three-dimensional computed tomographic angiography was helpful for decision making of selective coil embolization].
abstract: We reported the case of an 84-year-old female suffering from chemosis and exophthalmos. Carotid arteriograms revealed a direct carotid-cavernous fistula (CCF) but could not clearly show the fistula point because of its high-flow nature. We then performed three-dimensional computed tomographic angiography (3D-CTA) using a multi detector-row CT (MDCT) scanner. Multi-planar reformatted CT images distinctly revealed a right carotid aneurysm at the cavernous portion and a shunting point between the aneurysm and the cavernous sinus. Based on this information, we opted to performa transvenous coil embolization to treat this patient. Successful selective coil embolization was performed at the fistulous point was done with a smaller number of coils than ordinarily required in sinus packing. Performing 3D-CTA by using a MDCT was helpful in decision making for the selective coil embolization to treat direct CCF.
