The aim of this study was to evaluate the outcome of surgically treated dural arteriovenous fistula (DAVF). The authors performed surgical removal of DAVF in 12 patients. The locations of DAVF were the transverse sigmoid sinus in seven patients and superior sagittal sinus in five patients. These 12 patients had undergone endovascular embolisation prior to removal. Among them, six patients were completely cured, according to angiography immediately after embolisation, but these six patients showed the recurrence of DAVF within 1 year. The other six patients showed a decrease of feeding vessels. Therefore, all 12 patients underwent surgical removal of DAVF. The surgical strategies were as follows. The feeding vessels and the cortical veins with retrograde filling were occluded and cut. The affected sinus was skeletonised, and if it was occluded or almost occluded, the sinus was removed. Postoperatively, transient aphasia was seen in one patient. There was no surgical morbidity or mortality. During the follow-up period (mean 2.9 years), no recurrence of DAVF was seen. Surgical treatment is a safe and effective treatment manoeuvre for DAVF around the transverse sigmoid sinus and superior sagittal sinus.
