To assess the relationship between ventricular index (VI) measurements and postmenstrual age in preterm infants and to generate centile charts and normal ranges for frontal horn ratio (FHR) for a large contemporary cohort of preterm infants.
A retrospective cohort study of 253 infants with birth gestation less than 32 weeks admitted between January 2009 and December 2011 to a tertiary NICU in Ireland.
A total of 816 cranial ultrasounds were reviewed. Data collected were grouped according to postmenstrual age at the time of scan from 23 weeks to 45 weeks. Median values for VI show a general trend to increase with gestation. FHR did not significantly change with postmenstrual age at scan with a median value of 0.31.
There is a slight increase in VI as gestation at the time of scans increases. These results provide the basis for updated centile charts which we propose for current practice.
评估早产儿脑室指数（VI）测量值与孕龄之间的关系，并为大量当代早产儿队列生成额角比率（FHR）的百分位数图表和正常范围。
一项回顾性队列研究，研究对象为2009年1月至2011年12月间入住爱尔兰一家三级新生儿重症监护病房（NICU）的253例出生孕周小于32周的婴儿。
共回顾了816次头颅超声检查。收集的数据根据扫描时的孕龄分为23周龄至45周龄。VI的中位数显示出随孕周增加而增加的总体趋势。FHR在扫描时随孕龄无显著变化，中位数为0.31。
随着扫描时孕周的增加，VI略有增加。这些结果为我们建议在当前实践中使用的更新后的百分位数图表提供了依据。
