Abstract

OBJECTIVES
This report was designed to study the prognostic factors that affect the therapeutic results of dural arteriovenous fistula (DAVF).
METHODS
We retrospectively reviewed 97 patients who were treated for DAVF at our institute from January, 2000 to August, 2008. The DAVFs were usually located in four sites (cavernous sinus, transverse-sigmoid sinus, superior sagittal sinus and others). The diagnosis and the results of treatment were obtained by performing cerebral angiography.
RESULTS
The most common location of DAVF was the cavernous sinus (59.4%) and the next most common location was the transverse-sigmoid sinus (30.2%). Borden classification type II (72.2%) was most common and the next most common was type I (18.6%). Cortical venous reflux was abundant in the transverse-sigmoid sinus DAVFs and superior sagittal sinus DAVFs. Complete obliteration was achieved in 52 cases (55.3%) of all the 94 treated cases and incomplete obliteration was achieved in 42 cases (44.7%). Complete obliteration of the DAVF was achieved for 66.7% of the cavernous sinus lesions and in 41.4% of the transverse-sigmoid sinus lesions. Repeated treatments due to partial obliteration or recanalization were done in 18 cases.
CONCLUSION
Transverse-sigmoid sinus lesion and cortical venous reflux in a DAVF are closely related to the aggressive clinical features. Active treatment should be considered to treat these lesions. (ED note: some of this abstract was not clear and you need to check the revised abstract.)
