目的探讨超声确定中孕期胎儿脊髓圆锥的方法，分析孕中期胎儿脊髓圆锥末端的位置。方法选择60例孕中期单胎妊娠孕妇作为研究对象，所有孕妇均采用多普勒超声诊断仪分析脊髓圆锥位置，测量脊髓圆锥末端至骶尾部骨化中心距离。结果中孕期(19~24周)胎儿的脊髓圆锥末端位置多位于L2上缘至L4下缘之间，且伴随着孕周的不断增加，脊髓圆锥末端不断上移，孕23~24周胎儿的圆锥末端位置与孕19~20周比较差异具有显著性(P<0.05)；不同孕周脊髓圆锥末端至骶尾部骨化中心距离两两比较差异均具有显著性(P<0.01)；随着孕周的不断增加，脊髓圆锥末端至骶尾部骨化中心距离逐渐增加，增加距离为2~3mm。结论胎儿脊髓圆锥末端位置将伴随着胎儿孕周的增加而不断上移，利用脊髓圆锥末端至骶尾部骨化中心距离可有助于寻找脊髓圆锥位置。

Objective To explore the methods of determining the conus medullaris of trimester fetus by ultrasound ex-amination and analyze the position of conus medullaris. Method Select 60 singleton pregnancies in the second tri-mester visited the Third People's Hospital of Longgang District as the study object;all pregnant women were exam-ined by using the Siemens Acuson S2000 Doppler ultrasound machine for analyzing the position of conus medullaris and measuring the distance between conus medullaris end and the center of sacral bone. Result Most of the conus medullaris end of the trimester fetal (19~24 weeks pregnancy) were located between the lower edge of the L2 to L4, and increasing along with the gestational age, the conus medullaris end constantly moving up, compared with the conus medullaris end of the 23~24 weeks of pregnancy and 19~20 weeks of pregnancy, there was a significant statistical difference, P<0. 05;compared with the distance between conus medullals end and the center of sacral bone of different gestational age, there was a statistically different, P<0. 01;the distance between conus medullaris end and the center of sacral bone usually increased 2-3mm along with the gestational age increasing. Conclusion The conus medullaris end will be increased and constantly moving up accompanied by gestational age increasing. U-tilization of the distance between conus medullaris end and the center of sacral bone could help sonographer looking for conus medullaris position.
