전두와 경막 동정맥루의 수술적 치료 -증례보고-

Abstract

Objective : A dural arteriovenous fistula (DAVF) of the anterior cranial fossa is rare. We report a case of a DAVF of the anterior cranial fossa which was treated surgically, following endovascular treatment failure. Methods & Results : The subject was a 53-year-old male with a headache caused by a hematoma in the right frontal lobe. A vascular abnormality of the anterior cranial fossa was suspected on brain computed tomographic angiography. The subsequent transfemoral cerebral angiography revealed that the AVF of the anterior cranial fossa was mainly fed by the left anterior ethmoidal artery. Endovascular therapy using N-butyl cyanoacrylate was attempted. However, the procedure failed to occlude the fistula due to the existing feeding artery (the right anterior ethmoidal artery). Consequently, a surgical approach was undertaken and the lesion was successfully obliterated. Conclusion : We report a rare case of an intracerebral hematoma caused by a DAVF,which was successfully managed surgically following, endovascular treatment failure.
