Arterial spin-labeling imaging at 3-T in dural arteriovenous fistulas of cavernous sinus before and after endovascular treatment.

Arterial spin-labeling imaging at 3-T in dural arteriovenous fistulas of cavernous sinus before and after endovascular treatment. Hiroshima J Med Sci. 2012 Dec;61(4):105-7 Authors: Sakamoto S, Kiura Y, Okazaki T, Shinagawa K, Miyoshi H, Kurisu K Abstract A 72-year-old man presented with chemosis and ophthalmoplegia due to dural arteriovenous fistulas (DAVF) of the cavernous sinus (CS). Preoperative arterial spin-labeling (ASL) image showed visible vein in the bilateral superior ophthalmic vein (SOV). Endovascular transvenous embolization of the shunting points of the CS-DAVF was performed, and the postoperative angiogram showed complete obliteration of the CS-DAVF. Postoperative ASL showed no visible vein in the bilateral SOV. ASL in CS-DAVF was proved to have shown retrograde venous drainage from the CS-DAVF by comparing ASL before and after treatment.
