Stenting Procedure for Sinus Stenosis with Transverse-Sigmoid Dural Arteriovenous Fistulas

61-year-old male had been realizing the attack which causes bilateral visual problem. When he visited a hospital, it is pointed out that he suffered from the dural AVF in the transverse sinus and the intracranial hypertension, thus he was transferred to our hospital for the advanced treatment. The right external carotid angiogram shows the occlusion of right sigmoid sinus and the left transverse sinus stenosis, resulting in the reflux to the contralateral transverse sinus and SSS (figure 1A,B). Dural AVF elicits the impairment of the normal venous circulation. The flow in the straight sinus is anterograde, albeit a little weak, and runs into the left transverse sinus via the confluence (figure 1C,D). First of all TVE performed through the contralateral transverse sinus yielded the disappearance of the flow to the dural AVF from the right EC. This procedure caused any amelioration other than the ICP reduction from 41 cm H2O to 29 cm H2O. Angiography followed after the TVE still revealed the flow to the confluence from left EC and the mild proceeding of the left transverse sinus stenosis (figure 2A). Then, both TAE through the left EC and PTA/stenting procedure to the left transverse sinus stenosis were planned.
