在单卵双胎中，如果因为胎盘血管吻合，两个胎儿的血循环沟通发生血液转移，造成一胎贫血另一胎红细胞增多，称为双胎输血综合征、宫内联体综合征、贫血一红细胞增多综合征。其发病率为双胎的5％，围产期病死率极高，受血儿为88％，供血儿为96％，故临床意义重大。我院1994年1 In monozygotic twins, if the anastomosis of the placental vessels, blood circulation occurs between the two fetuses blood transfer occurs, resulting in another fetal anemia, an increase of red blood cells, known as twin transfusion syndrome, intrauterine mass syndrome, anemia Erythrocyte syndrome. Its incidence rate of 5% of twins, perinatal mortality is extremely high, by the blood of 88%, for 96% of children, it is clinically significant. Our hospital in 1994 1
