- 研究ARSA对胎儿生长和发育的影响.
主要方法:
- 未来病例控制研究涉及93名胎儿 (40个孤立的ARSA,53个对照).
- 使用多普勒超声波测量胎儿的血液动力学参数:最大静脉缩速度 (PS),脉率指数 (PI),阻力指数 (RI),时间平均最大速度 (TAMAX) 和心率 (HR).
- 在ARSA和对照组之间比较多普勒参数,分析与妊娠年龄和胎儿体重的相关性.
主要成果:
- 在隔离ARSA和对照的胎儿之间没有观察到PS,PI,RI,TAMAX或HR的统计学上显著差异.
- 在任何一组中,妊娠年龄,胎儿体重和测量的多普勒参数之间没有发现相关性.

4.0K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

2.8K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

01:07Development of Blood Vessels
1.7K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
