胎儿和婴儿股骨近端的静脉及其临床意义

The Veins on the Proximal End of Femur and Their Importance in Fetus and Infant

对54侧8个月胎儿至1岁儿童股骨近端的静脉进行了研究。股骨近端的静脉与其动脉伴行。骨内静脉先以静脉网套在小动脉外周,再汇集成一或二条静脉与动脉伴行引流至骨外。骨外回流途径包括前、后、内侧和外侧颈升静脉,股骨头韧带静脉,闭孔静脉,臀上、下静脉,旋股内、外侧静脉。结合静脉分布特点,对髋部某些疾病的发病机制进行了讨论。

The veins on the proximal end of femur in 54 specimens ranging in age from eight months of gestation to one year were studied.These veins were accompanied by the corresponding arteries.The tiny intraosseous veins formed a venous network surrounding and accompanying the arterioles,and drained into the veins outside the cartilage.The extraosseous veins on the proximal end of femur drained into the adjacent veins.Some possible pathogenic mechanism related to the above characteristcs of the venous distribution in fetus and infant were discussed.
