We treated 7 cases of dural arteriovenous fistulas (dAVF) with isolated sinus by transvenous direct embolization.
The fistulas located in the transverse-sigmoid sinus in 5 cases, superior sagittal sinus in 1 case and transverse-sigmoid and superior sagittal sinus in 1 case.
The initial symptoms were generalized convulsion in 2 cases, disturbed consciousness in 1 case, tinnitus in 2 cases and transient ischemic attack in 2 cases. We performed sinus packing with coils in all cases following transarterial embolization.
All patients improved neurologically after the treatments and AVFs completely disappeared in all cases.
