摘　　要：目的　探讨超声、CT及MRI检查在眼上静脉扩张及其病因诊断中的意义。方法　对1984～ 2 0 0 0年临床资料完整的 116例 (2 32只眼 )伴眼上静脉扩张患者进行回顾性分析。结果　发现多种疾病均可引起眼上静脉扩张 ,颈动脉 海绵窦瘘是导致眼上静脉扩张的主要疾病。其中颈动脉 海绵窦瘘 92例 (包括高和低流瘘 ) ,眼型Graves病 14例 ,眶尖炎症 2例 ,Tolosa Hunt综合征 2例 ,眼部血管畸形 2例 ,眶炎性假瘤、眶内血肿、海绵窦肿瘤及海绵窦血栓形成各 1例。扩张的眼上静脉直径为 3 5～ 7 0mm ,各病种眼上静脉管径扩张大小无明显差异 ,但颈动脉 海绵窦瘘眼上静脉最粗 7 0mm。影像学检查同时能发现眼外肌肥大、眶部病变及海绵窦膨大等相关影像学表现。结论　超声、CT及MRI检查均能良好显示眼上静脉扩张 ,综合其他影像学表现 。Objective To evaluate the diagnostic value of CT, MRI and Doppler ultrasound in dilatation of superior ophthalmic vein (SOV) and its etiologies. Methods One hundred and sixteen cases of enlarged SOV were analyzed with regard to imaging techniques. Results SOV enlargement was noted to occur in carotid cavernous fistula (92 cases), ophthalmic Graves′ disease (14), Tolosa Hunt syndrome (2), inflammation at the apex of the orbit (2), ocular vascular deformity (2), orbital pseudotumor (1), orbital hematoma (1), cavernous sinus tumor (1) and thrombosis of cavernous sinus (1). The dilated vein appeared as signal void tubular shadows on both T 1 and T 2 weighted images. The diameter of the enlarged vein was 3 5-7 0 mm. Extraocular muscle enlargement, orbital lesions, enlarged cavernous sinus, etc were also revealed by MRI, CT and B ultrasound scan. Conclusions The dilated SOV may be well demonstrated by MRI, CT and ultrasound scanning. The etiological diagnosis of enlarged SOV can be made in combination with the associated findings. The authors suggest that some carotid cavernous fistula cases be occluded by retrograde embolization via the SOV route.
