We performed percutaneous umbilical blood sampling, under ultrasound guidance, in both twins of 11 twin pregnancies in whom twin-to-twin transfusion syndrome was suspected. Chorionicity and the presence of placental vascular anastomoses were assessed postnatally. The hemoglobin concentration, hematocrit and other biochemical variables in fetal blood were evaluated in both twins. The mean hemoglobin difference between the large and small twins was 4.8 g/dl (range 1.8-8.1 g/dl) in 5 monochorionic discordant twin pairs, and 1.2 g/dl in a monochorionic twin pair without discordancy. Hemoglobin values did not differ between dichorionic twins. The mean hematocrit difference between monochorionic discordant twins was 18.3%. In dichorionic discordant twins, the inter-twin hematocrit difference was very small. Total protein and albumin were normal in all twins.
我们在超声引导下，对11例疑似双胎输血综合征的双胎妊娠中的两个胎儿均进行了经皮脐血采样。产后评估绒毛膜性及胎盘血管吻合情况。对两个胎儿的血红蛋白浓度、血细胞比容及其他血液生化指标进行了评估。5例单绒毛膜双羊膜囊双胎输血不一致的双胎中，大胎儿与小胎儿之间的平均血红蛋白差值为4.8 g/dl（范围1.8 - 8.1 g/dl），1例单绒毛膜双羊膜囊双胎输血无不一致情况的双胎中平均血红蛋白差值为1.2 g/dl。双绒毛膜双胎之间血红蛋白值无差异。单绒毛膜双羊膜囊双胎输血不一致的双胎之间平均血细胞比容差值为18.3%。双绒毛膜双羊膜囊双胎输血不一致的双胎之间，双胎血细胞比容差值非常小。所有双胎的总蛋白和白蛋白均正常。
