概括

双胞胎对双胞胎输血综合征 (TTTS) 可能会减少母亲的循环血液量. 在单胆双胞胎怀孕中,在TTTS期间,母亲的心脏功能适应保持心脏输出.

科学领域:

孕产妇和胎儿的医学
心脏病学心脏病学
产科产科产科产科产科

背景情况:

双胞胎怀孕显著改变了母亲的血液循环.
双胞胎对双胞胎输血综合征 (TTTS) 是单胞胎双胞胎怀孕的一个并发症.
对于TTTS对孕产妇血液循环的具体影响仍然不完全理解.

研究的目的:

为了研究 TTTS 发病时母亲的循环系统变化.
为了比较单子,无并发的MD双胞胎和TTTS怀孕中的母亲心脏功能.

主要方法:

前性队列研究包括单个,不复杂的MD双胞胎和TTTS组.
对左心室功能,收缩性和扩张性能的心声评估.
测量下腔静脉直径和心率.

主要成果:

与没有并发症的MD双胞胎组相比,TTTS组表现出明显较低的左心室末缩体积.
在没有并发症的MD双胞胎组中,左心室喷射率明显低于TTTS组.
在TTTS组中,心率显著升高,而心率在所有组中仍然相似.

结论:

怀有TTTS的双胞胎怀孕可能与母亲循环血液体积的减少有关.
在TTTS的存在下,母亲的心脏功能显示出适应机制来维持心脏输出.

Fetal Circulation

Fetal Circulation

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...
