研究目的:

通过超声监测GDM孕妇胎儿大脑外侧裂等神经结构变化,评估胎儿神经系统发育情况,可以指导临床及早干预,降低妊娠并发症、提高母儿围生期安全。  

Objectives of Study:

Ultrasound monitoring of changes in fetal neuroanatomical structures, such as the lateral sulcus, in pregnancies complicated by gestational diabetes mellitus (GDM) can be used to assess fetal neurodevelopment. This approach may help guide early clinical intervention, reduce pregnancy-related complications, and improve maternal and perinatal outcomes.

指标中文名:

双顶径

指标类型:

次要指标

Outcome:

Biparietal diameter

Type:

Secondary indicator

测量时间点:

进行常规产检时

测量方法:

取胎头丘脑水平横切面(标准平面需显示丘脑及透明隔腔),图像左右对称,中线居中。测量方法为近场颅骨外缘至远场颅骨内缘(外-内径)

Measure time point of outcome:

During routine antenatal care

Measure method:

Measured on the standard transverse plane of the fetal head at the level of the thalami and cavum septi pellucidi. The image should be symmetrical, with the midline echo centrally positioned. BPD is measured from the outer edge of the proximal skull table to the inner edge of the distal skull table (outer–inner method).

指标中文名:

大脑外侧裂

指标类型:

主要指标

Outcome:

Sylvian Fissure

Type:

Primary indicator

测量时间点:

进行常规产检时

测量方法:

外侧裂深度:以胎儿丘脑水平横切面为基准,以外侧裂高回声线最后端为顶点,作垂直于脑中线的垂线,在此垂线上外侧裂顶点到颅骨内缘的距离为外侧裂深度。

Measure time point of outcome:

During routine antenatal care

Measure method:

Lateral sulcus depth: Using the transverse plane at the level of the fetal thalamus as the reference, the terminal point of the hyperechoic line of the lateral sulcus was identified as the vertex. A line perpendicular to the midline of the brain was drawn, and the distance from the vertex of the lateral sulcus to the inner table of the skull along this perpendicular line was defined as the depth of the lateral sulcus.
