双胎输血综合征(twin-to-twin transfusion syndrome,TTTS)是单绒毛膜双羊膜囊双胎妊娠的严重并发症。两个胎盘之间存在血管吻合包括动脉间、静脉间及动静脉吻合3种。大约有10%~15%~([1])的单绒毛膜多胎妊娠发生TTTS。受血胎儿表现为循环血量增加,羊水过多,心脏扩大或心衰伴有水肿;而供血胎儿表现为循环血量减少,羊水过少,生长受限。有时供血儿出现羊水严重过少,被挤压到子宫的一侧,成为“贴附儿”(stuck-twin)。 Twin-to-twin transfusion syndrome (TTTS) is a serious complication of twin-fetu twin pregnancy. There are vascular anastomosis between the two placenta including arterial, venous and arteriovenous anastomosis 3. About 10% to 15% ~ ([1]) of the single choriocarcinoma occurs TTTS. The performance of the fetus by the blood circulation increased blood volume, polyhydramnios, heart enlargement or heart failure accompanied by edema; and blood supply to the fetus showed reduced circulating blood volume, oligohydramnios, limited growth. Sometimes there is a serious shortage of amniotic fluid supply, squeezed to the side of the uterus, become “stuck-child” (stuck-twin).
