a vein that begins at the inner angle of the eye socket and passes through the superior orbital fissure to empty into the cavernous sinus

objective:to provide microanatomy data for treatment of carotid-cavernous sinus fistulas using a superior ophthalmic vein approach.

目的：为经眼上静脉行海绵窦动静脉瘘栓塞提供显微解剖学依据。

methods a retrospective analysis was made of 94 patients with superior ophthalmic vein enlargement who were examined by color doppler ultrasonography from 1996~2005.

方法对1996~2005年经彩色多普勒超声检查明确眼上静脉扩张的94例眼眶病患者进行回顾性分析。

feeding arteries detected by cdfi counted up to 42 branches ( 72.4%). the venous drainage through transverse sinus and superior ophthalmic vein were all detected.

供血动脉检出42支（72.4%），经横窦及眼上静脉的引流均检出，经上矢状窦及皮层静脉的引流均未能检出；

the cavernous sinus portion of superior ophthalmic vein had the structure of venous sinus.

眼上静脉海绵窦段具有静脉窦结构。

objective to evaluate the value of color doppler ultrasound in dilated superior ophthalmic vein and its etiologies.

目的探讨彩色多普勒超声检查对眼上静脉扩张及其病因的诊断价值。

results the enlarged cavernous sinus and the enlarged superior ophthalmic vein appear distinctly in the same plane, that is the characteristic appearance of arteriovenous fistula in cavernous sinus.

结果扩张变形的海绵窦与曲张的眼上静脉在同一层面清晰显示。

in 60 intracranial hypertension patients, 21 cases(35%) displayed superior ophthalmic vein in double axial layers continuously and 8 cases(13.3%) showed tortuosity of superior ophthalmic vein.

颅内压增高患者中21例（35%）眼上静脉在球后相同位置连续双层面显示，8例（13.3%）眼上静脉的走行发生改变。
