胎儿新生儿股骨近端血运分布的研究

A Study of Vascular Contribution to the Proximal End of the Femur in Fetus and Neonates

股骨近端的血运供应对髋关节的发育及某些疾病的发生十分重要,Trueta(1)Ogden(2)Chung(3)等曾报道生长时期殷骨近端的血运分布,但对不同时期的胎儿和新生儿血运变化的特点至今尚未见劲.本文通过灌注造影,切片观察探讨了胎儿新生儿股骨近端血运变化的特点,为研究一些髋关节疾病的病理提供了解剖学基础,也是探讨胎儿发育的重要资料.

Perfusion method was used in a study of the blood supply of the proximal end of the femur in 52 cadaver specimens taken from the induced abortions and newborn deaths, with age ranging from the 16th fetal week to full term. X-ray films were taken in 45 cadavers: and sections prepared from all the specimens. They were divided into 4 groups for compari-son and analysis. The authors conclude that: 1. epiphyseal arteries are the main blood supply to the femoral head in fetus and neonates, and 2. the formation of capillary loops between metaphysis and the base of hypertrophic layer of the growth-plate is completed by the 16th fetal week. An observation on the shape and structure of the cartilage canals was carried out in the fetus and neonates, The origins of the blood vessels and streaks within the epip-hyseal plate and the theory of the blood barrier between epiphysis and metaphysis were discussed. Besides, clinical and pathological signif-icance of the cartilage canals is also discussed.
