双胎输血综合征是指单合子单绒毛膜双羊膜囊双胎,在宫腔内一胎儿(供血儿)通过胎盘不平衡的血管吻合网将血液输送给另一胎儿(受血儿),而引起的一系列病理生理改变和临床症状,是双胎或多胎妊娠的严重并发症。此病预后较差,很大程度上是源于其病因和病理生理还不十分清楚,以及临床上缺乏有效的治疗手段。目前诊断主要靠产前超声和产后胎儿、胎盘检查,现有的治疗方法较多,应用较多的是胎儿镜下选择性激光电凝、羊水减量、羊膜造口等,每种方法都有其优缺点和优选的时间,但为了改善该病的预后,还需在深入研究病因及病理生理的基础上,找出更合理可行的治疗方法。
Twin twin transfusion syndrome refers to the monozygotic mononuclear double amniotic sac twins, in the uterine cavity of a fetus (blood supply) through the placental imbalance of vascular anastomosis network to the other side of the blood to the fetus (by the blood), and Caused by a series of pathophysiological changes and clinical symptoms, twin or multiple pregnancy is a serious complication. The poor prognosis of the disease, largely due to its etiology and pathophysiology is not yet very clear, and the lack of effective clinical treatment. The current diagnosis mainly depends on prenatal ultrasound and postpartum fetus, placenta accreta, the existing treatment methods are more applied more selective laser coagulation, amniotic fluid reduction, amniotic stoma, each method has Its advantages and disadvantages and the preferred time, but in order to improve the prognosis of the disease, it is necessary to further study the etiology and pathophysiology, to find out more reasonable and feasible treatment.
