研究目的: |
设计一种新的产前超声评估脐带螺旋的量化指标(imUCI)并探索其预测脐带形态学异常的临床应用价值,并与旧指标进行对比。探索新指标(imUCI)与不良围产结局的相关性,纳入imUCI结合其他超声及临床指标建立不良围生结局的临床预测模型。 |

|
Objectives of Study: |
A new quantitative index of prenatal ultrasound for the evaluation of umbilical cord helix (imUCI) was designed and its clinical application value in predicting umbilical cord morphological abnormalities was explored, and compared with the old index. To explore the correlation between the new index (imUCI) and adverse perinatal outcomes, and to include imUCI in combination with other ultrasound and clinical indicators to establish a clinical prediction model of adverse perinatal outcomes. |

纳入标准: |
1.孕期为28周至分娩前(定期常规产检且末次月经时间清楚,孕周准确无误); 2.单胎妊娠 经产前超声检查无严重胎儿畸形,脐带由两条脐动脉及一条脐静脉构成且可显示段至少需要有两个螺旋以上; 3.羊水足够充沛,能清晰显示近脐轮处的脐带(至少显示完整的一个螺旋)。 4.在上述医院分娩,临床各项资料完整。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. The pregnancy period is from 28 weeks to before delivery (regular routine prenatal check-ups, the last menstrual period is clear, and the gestational week is accurate) ; 2. Singleton pregnancy No serious fetal malformations on prenatal ultrasound, the umbilical cord is composed of two umbilical arteries and one umbilical vein, and the visible segment needs to have at least two spirals; 3. The amniotic fluid is sufficient to clearly show the umbilical cord near the umbilical chakra (at least one full spiral is shown). 4. Delivery in the above-mentioned hospitals, complete clinical information. |
||||||||||||||||||||||
|
排除标准: |
1.单脐动脉或脐血管数量有其他异常的孕妇 2.因羊水过少等因素无法清晰显示近脐轮处的脐带或无法获得满意超声图像的孕妇。 3.不能随访到胎儿出生后情况及临床资料缺失的孕妇 4.每位孕妇均只进行一次产前超声检测,在最后的数据整理中排除掉在不同孕周进行过两次以上超声检测的孕妇。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Pregnant women with a single umbilical artery or other abnormalities in the number of umbilical vessels 2. Pregnant women who are unable to clearly display the umbilical cord near the umbilical chakra due to oligohydramnios and other factors or who are unable to obtain satisfactory ultrasound images. 3. Pregnant women who could not be followed up after birth and lack of clinical data 4. Only one prenatal ultrasound test was performed for each pregnant woman, and pregnant women who had undergone more than two ultrasound tests at different gestational weeks were excluded in the final data collation. |
