双胎输血综合征是指由于单卵双胎胎盘血管吻合,血流分布不均衡,导致一个胎儿呈多血状态,而另一个胎儿呈贫血状态的一组综合征。在人们认识双胎输血综合征以前,Schatz 在1882年就已发现单绒毛膜双胎胎盘多有血管吻合现象。1942年Herlitz 对本征首次作了报告,随后有许多学者对此征进行了详细的观察和研究。多数学者认为,产生本征的原因主要是胎盘中存在所谓第三循环,即除母体循环,胎儿循环外还存在着两个胎儿间的血液循环。随着围产医学的发展,人们逐渐开始重视由此产生
Twin blood transfusion syndrome is due to monozygotic twin placental vascular anastomosis, uneven distribution of blood flow, leading to a fetus was multi-blood state, while another fetus was anemic group of syndrome. Before people knew twin blood transfusion syndrome, Schatz had discovered in 1882 that there was more blood vessel anastomosis in monoclasp twin placenta. In 1942, Herlitz made the first report on the eigenvalue, and many scholars subsequently conducted a detailed observation and research on the issue. Most scholars believe that the main cause of the etiology is the so-called placenta in the so-called third cycle, that is, in addition to the maternal cycle, the fetus also exists outside the blood circulation between the two fetuses. With the development of perinatal medicine, people gradually began to attach importance to the resulting
