超声观察中孕期胎儿大脑外侧裂深度与孕周关系

Ultrasound Observe the Relationship between Fetus Cerebral Lateral Fissure Depth in Middle Pregnancy and Gestational Weeks

[目的]超声观察中孕期胎儿大脑外侧裂的深度与孕周的关系，为产前早期评估胎儿大脑皮质的发育正常与否提供资料，以供同行进一步探讨。[方法]对2011年2月至2013年9月产前常规检查的559例孕期18～24周孕妇经腹部超声观察胎儿大脑外侧裂的形态，并在小脑横切面测量其深度。[结果]超声观察559例孕妇中孕期胎儿大脑外侧裂的深度随孕周增加呈递增趋势，形态由平滑渐变为圆顿。[结论]超声观察胎儿大脑外侧裂深度随孕周增加而加深，可作为产前早期评估胎儿大脑皮质的发育正常与否提供正相关系资料。

[Objective] To observe the relation between the fetus cerebral lateral fissure depth in middle pregnancy and gestational weeks and offer foundation for whether or not normal growth of fetus cerebral cortex in antenatal early evaluation. [Method] Observe the shape of fetus cerebral lateral fissure of 18~24w pregnant women 559 cases with ultrasound, and measure the depth at cerebel um cross section. [Result] The 559 cases of pregnant women ’s fetus cerebral lat-eral fissure depth increases with gestational weeks, the shape changes blunt from smooth. [Conclusion] The ultrasound observation of fetus cerebral lateral fis-sure depth which increases with gestational weeks can be taken to offer relative basis for early evaluation of whether or not normal cerebral cortex growth.
