Subjects and Methods: A prospective, uncontrolled study including 18 patients with DAFoCS treated by endovascular intervention from January 2016 to June 2017 in the Radiology department at BMH. Result: 9 cases presented at transverse and sigmoid sinus (49.9%), 3 cases at superior sagittal sinus (16.7%), 1 case at spheno-palatine vein (5.5%), 5 cases at the other dural venous sinuses (27,8%). 50% of the cases have feeding arteries from branches of the ECA
the other cases have mulbple feeding arteries (ECA, ICA, vertebral artery, etc.). According to Cognard ciassificabon: 16,7% type I, 11,1% type IIa, 33,3% type IIb, 33,3% type IIa + b, 5,5% type III. 6 cases (6/18, 33.3%) had venous thrombosis.
