A 49-year-old female presented with proptosis and slight chemosis with diplopia on the right. The patient had a past history of skull base fracture occurring one year before the onset of the symptoms. Magnetic resonance imaging showed a partially thrombosed varicose aneurysm (varix) of the superior ophthalmic vein (SOV). Carotid angiography showed a pseudoaneurysm in the right cavernous sinus, associated with slow flow carotid-cavernous sinus fistula via the SOV. Proptosis was due to the direct mass effect of the thrombosed varix of the SOV. The thrombosed varix was removed after right carotid artery trapping with external carotid artery-middle cerebral artery (M(2)) high flow bypass. The symptoms subsided after the surgery.
一名49岁女性出现右眼眼球突出、轻度球结膜水肿及复视。该患者在症状出现前一年有颅底骨折病史。磁共振成像显示眼上静脉（SOV）有部分血栓形成的静脉曲张性动脉瘤（静脉瘤）。颈动脉血管造影显示右侧海绵窦有假性动脉瘤，通过SOV与缓慢血流的颈内动脉海绵窦瘘相关。眼球突出是由于SOV血栓形成的静脉瘤的直接占位效应。在右侧颈动脉阻断并进行颈外动脉-大脑中动脉（M(2)）高流量搭桥术后，切除了血栓形成的静脉瘤。术后症状缓解。
