摘要
解剖了35例成人眶腔的眼上静脉,多数呈一千型,占94.29±0.12％。该静脉的重要属支有内上涡状静脉和外上涡状静脉,内上涡状静脉汇入部位与上斜肌滑车之间距值为12.80±0.48mm。外上涡状静脉汇入部位与视神经孔外缘上端之间距值为20.46±0.98mm。发现眼上静脉干中,眶上静脉汇入处和其与内眥静脉交通支的相连处,有成对的半月形瓣膜者占11.43±3.98％,瓣窦开口向海绵窦。
The superior ophthalmic vein was dissected in 35 adult Chinese orbits.The vein mainly presents the form of one stem,accounting for 94.29±0.12％.The important tributaries of the superior ophthalmic vein are medial and lateral superior vorticose veins. The average distance between the point at which the medial superior vorticose vein drains into superior ophthalmic vein and the trochlea of the superior oblique muscle measures 12.80±0.48mm.The average distance between the point at which lateral superior vorticose vein drains into superior ophthalmic vein and superior end of lateral edge of optic foramen measures 20.46±0.98mm.Semilunar valves opening towards the cavernous sinus were found in the middle of the superior ophthalmic vein and the area at which the supraorbital vein and angular vein drains into superior ophthalmic vein,accounting for l1.43±3.98％.
