【摘要】：目的评价超声测量正常胎儿长骨骨干长度及总长度与引产后X线测量长度及裸骨的相关性。方法选择孕周20-38周423例长骨发育正常的胎儿,应用二维超声常规测量长骨骨干长度及其干骺端结构的长度,并计算总长度。其中51例引产儿(20-32周)纳入本次研究。引产后24小时内将引产病例做尸体X线摄片检查测量长骨长度,并测量其裸骨长度(包括干骺端结构)及裸骨X线长度,超声测量总长度与引产后尸体X线摄片的长骨长度、裸骨长度及裸骨X线长度作对比。结合临床资料将几种测量结果做统计学分析。研究过程中,将部分引产后胎儿置于水中,模拟宫内环境观察胎儿长骨及干骺端结构的形态学特征,部分新鲜裸骨同样放置水中以高频超声观察长骨回声及其两端干骺端结构的特征。结果超声观察宫内或离体胎儿肢体长骨骨干及干骺端结构的形态学特征与X线及裸骨观察结果基本一致,但长度及干骺端结构可清晰显示。超声测量长骨骨干值及裸骨长度分别与尸体长骨X线测值比较,差异均具有统计学意义(P0.05),尸体长骨X线测值大于超声测量长骨骨干值,小于裸骨长度：将超声测量长骨总长度、裸骨X线测值分别与裸骨长度比较,差异均无统计学意义(P0.05)。相关性分析结果显示超声与裸骨测量长度存在高度正相关。结论超声可精确测量骨干及干骺端结构的长度。产前超声、尸体X线摄片及裸骨三种方法测量结果不完全一致,但三者之间有一定相关性。尸体X线测量不能反映长骨真实的总长度,而超声测量长度总长度与裸骨测量结果基本一致,且超声测量与裸骨测量方法的相关性也较好,可更真实地反映胎儿长骨发育情况,从而有助于更准确评价胎儿生长发育迟缓及短长骨。
[Abstract]:Objective to evaluate the ultrasound measurement of normal fetal long bone length and the total length of gestation with bare bone length and X-ray measurement after correlation. Methods 20-38 weeks of gestation in 423 cases of normal fetal long bone development, application of two-dimensional ultrasound measurement of long bone length and metaphyseal structure length, and calculate the total length. Among them 51 cases cited infants (20-32 weeks) were included in the study. Labor within 24 hours after the induction of case body X-ray measurement of long bone length, and measuring the bare bone length (including metaphyseal structure) and bare bone X-ray length, total length of ultrasonic measurement and autopsy long bone X-ray, bare bones the length and the length of bare bone X-ray compared with clinical data. Several measurement results were statistically analyzed. The course of the study, will be part of the induction of labor after fetal intrauterine environment simulation in water, observation of fetal long bone and metaphyseal structure form Features, some fresh bare bones also placed in water to observe the characteristics of the long bone metaphyseal structure echo and the two stem with high frequency ultrasound. Results the ultrasound observation of intrauterine fetal limb long bone or isolated diaphyseal and metaphyseal structure morphology and X-ray and bare bone observation results are basically the same, but the length and metaphyseal structure can be clearly displayed. Ultrasonic measurement of long bone value and bare bone length and body bone X-ray measurements were compared, the differences were statistically significant (P0.05), the body bone X-ray measured value is greater than the ultrasonic measurement of long bone values less than bare bone length: the total length of ultrasonic measurement of long bone, bare bone X-ray measurements were compared with the bare bone length, there were no significant differences (P0.05). The results of correlation analysis showed that there was a strong positive correlation with ultrasonic measuring the length of bare bone. Conclusion ultrasound can accurately measure the diaphyseal and metaphyseal structure. The length of prenatal ultrasound, The body X-ray and the bare bones of three measuring methods were not completely consistent, but there is a certain correlation between the three bodies. The total length of the long bone X-ray measurement can not reflect the true, and the length of the total length of ultrasonic measurement results are basically consistent with the bare bone, also a good correlation and ultrasonic measurement and measurement method of the bare bone, can reflect fetal long bone development, thus contributing to a more accurate assessment of fetal growth retardation and short long bones.
