摘要
通过动脉灌注,对100侧不同年龄(新生儿~67岁)尸体的股骨近侧端的血液供应进行了研究。囊外动脉环围绕股骨颈基部,由旋股内、外侧动脉组成,完整者占71%;囊内动脉环位于关节软骨缘滑膜下,由内侧、后、外侧和前颈升动脉组成,多见此环前部、后部和前、后部合并缺损,占74%。外骺动脉向关节软骨发出多级动脉弓,分布于股骨头的上、内、中央和外侧区。内侧颈升动脉分布于股骨头下后区。内骺动脉分布于有限的股骨头凹下区。关节软骨游离面由接近关节软骨缘和股骨头凹周缘的滑膜血管网及滑液营养,它的深部近骨—软骨接合处,由骺毛细管襻供给营养。上干骺部动脉分布于股骨颈外2/3,内侧颈升动脉和前、后颈升动脉短支分布于股骨颈相应区。在骺软骨骨化过程中,骺动脉与内侧颈升动脉在骨骺中建立一定的吻合弓。骺软骨板在成年骨化后消失,干骺部动脉穿入骨骺,与骺动脉建立广泛吻合。本文对股骨近侧端动脉的形态、行经、分布及其与临床的意义进行了讨论。
