Endovascular treatment of carotid cavernous sinus fistula: A systematic review

Figure 4 A forty-year-old woman with chemosis of the left eye and diplopia was found to have a dural carotid cavernous sinus fistula. A, B: Frontal (A) and lateral (B) injections of the right common carotid artery demonstrating left dural carotid cavernous sinus fistula with antegrade drainage; C: Access to the fistula site through the contralateral (right inferior petrous sinus) transvenous route and positioning of the microcatheter; D: Coil embolization within the microcather extending into the venous compartment of the fistula; E: Posttreatment frontal digital subtraction angiogram view of right internal carotid artery demonstrating obliteration of the fistula and lack of residual filling.
