Abstract

Background: With the invention of more sophisticated ultrasonography techniques, there is room to explore and better comprehend the link between gestational age (GA), fetal weight (FW), and the diameter of the umbilical vein (UV). Aim: To explore the relationship between umbilical vein diameter (UVD) and GA as well as FW in normal pregnancy. Materials and Methods: This descriptive, cross-sectional study was conducted between February and August 2022 at the obstetric units and radiology departments of two tertiary health facilities: one secondary facility and one radiodiagnostic facility in the state. A transabdominal ultrasound scan was used to assess the UV. The relationship between UVD and GA and between UVD and estimated fetal weight (EFW) was explored using Pearson's correlation analysis. A nomogram was constructed, and the level of significance was set at P < 0.05. Results: There was a very strong, positive and significant relationship between UVD and GA (r =0.63; P = 0.001) and between UVD and EFW (r = 0.57; P = 0.001). For every unit change in GA, there was a 39% change in UVD (r2 = 0.39), while every unit change in FW was associated with a corresponding 33% change in UVD (r2 = 0.33). The regression coefficients for GA were 0.257 (β0) and 0.015 (β1), while β0 and β1 for FW were 0.590 and 0.069, respectively. Conclusion: Our study revealed a very strong, positive and significant relationship between UVD and GA and between UVD and EFW.
正常妊娠脐静脉直径的超声测量及其与胎龄和胎儿体重的相关性
背景:随着更复杂的超声技术的发明,有空间探索和更好地理解胎龄(GA)、胎儿体重(FW)和脐静脉直径(UV)之间的联系。目的:探讨正常妊娠脐静脉直径(UVD)与GA及FW的关系。材料和方法:这项描述性的横断面研究于2022年2月至8月在两个三级卫生机构的产科和放射科进行:一个二级卫生机构和一个放射诊断机构。使用经腹部超声扫描来评估紫外线。应用Pearson相关分析探讨了UVD与GA之间以及UVD与估计胎儿体重(EFW)之间的关系。构建列线图,并将显著性水平设定为P<0.05。结果:UVD与GA(r=0.63;P=0.001)和UVD与EFW(r=0.57;P=0.001,β0和β1分别为0.590和0.069。结论:我们的研究揭示了UVD和GA以及UVD和EFW之间非常强烈、积极和显著的关系。
