REQUEJO, Flavio; FONTANA, Horacio; BELZITI, Héctor  e  RECCHIA, Mario. Fístulas durales de la proximidaddel seno sagital superior.: revisión selectiva. Rev. argent. neurocir. [online]. 2006, vol.20, n.2, pp.69-73. ISSN 1850-1532.

Weperformed a selective bilbiographic review about dural fistulas that involvedthe superior sagital sinus to know its phisiopathology, clinical symptoms,diagnosis and treatment. The dural fistula of the region of the superiorsagittal sinus is a vascular anomaly characterized by an abnormalarteriolarvenous communication in the dura mater near the sinus wall. Becauseof the arterialized cerebral veins, intracranial hemorrhage is the most commonform of presentation of this infrequent disease. Feeding arteriolar rami fromthe superficial temporal and meningeal arteries commonly come from both sides.In these cases the anomaly lies in the sinus wall without involvement of thesinus lumen. Less frequently leptomeningeal rami of the internal carotid and orvertebral artery feed the fistula. In these patients, the sinus is totally orpartially occluded and the veins are filled with arterial blood by reflux. Acomplete and selective angiography is mandatory when this illness is suspected.The goal of the treatment is to eliminate the arterial flow in the cerebralveins. It can be accomplished by means of surgical or endovascular methods,through the arterial or venous side.
