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.
一名72岁男性因海绵窦硬脑膜动静脉瘘（DAVF）出现结膜水肿和眼球运动障碍。术前动脉自旋标记（ASL）图像显示双侧眼上静脉（SOV）可见静脉。对海绵窦DAVF的分流点进行了血管内静脉栓塞，术后血管造影显示海绵窦DAVF完全闭塞。术后ASL显示双侧SOV未见静脉。通过比较治疗前后的ASL，证实海绵窦DAVF的ASL显示了来自海绵窦DAVF的逆行静脉引流。
