Abstract

Purpose: This study aims to investigate the fetal Evans Index and establish a nomogram for fetuses without any additional fetal anomalies detected during the prenatal period.

Methods: We conducted our research at Ankara City Hospital, including 894 patients who were admitted and evaluated between gestational weeks 16-40. These patients had no fetal anomalies detected in subsequent gestational weeks. Descriptive data, such as age, gravidity, parity, and body mass index (BMI), were recorded. Gestational week and Evans Index (mean, median, standard deviation, minimum, maximum, and percentile) were also documented. The Evans index was calculated as the ratio between the maximal width of the frontal horns and the maximal width of the inner diameter of the cranium.

Results: We evaluated 894 fetuses in pregnant women had no fetal anomalies detected throughout the pregnancy. The evaluation took place at different gestational weeks, and a nomogram for the Evans Index was created.

Conclusions: It is relevant for clinicians and researchers to be aware of the range of fetal Evans Index values across different gestational weeks as a prognostic criterion.

开发胎儿埃文斯指数提名图。

目的：本研究旨在调查胎儿埃文斯指数，并为产前未发现任何其他胎儿畸形的胎儿建立一个提名图：我们在安卡拉市医院进行了研究，包括 894 名在孕 16-40 周期间入院并接受评估的患者。这些患者在随后的孕周未发现胎儿畸形。记录了描述性数据，如年龄、孕周、胎次和体重指数（BMI）。此外，还记录了孕周和埃文斯指数（平均值、中位数、标准差、最小值、最大值和百分位数）。埃文斯指数的计算方法是额角最大宽度与颅骨内径最大宽度之比：我们对 894 名孕妇的胎儿进行了评估，整个孕期均未发现胎儿畸形。评估在不同孕周进行，并绘制了埃文斯指数的提名图：临床医生和研究人员有必要了解不同孕周胎儿埃文斯指数值的范围，以此作为预后标准。

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
