To review the perinatal outcome of monochorionic twin pregnancies treated by fetoscopic laser coagulation for twin-twin transfusion syndrome.
Retrospective study.
A university teaching hospital in Hong Kong.
Thirty consecutive cases of fetoscopic laser coagulation of placental anastomoses for twin-twin transfusion syndrome performed in a single centre.
Operative complications and perinatal survival rates.
The median gestational age at initial presentation, laser photocoagulation, and delivery were 22 (range, 16-27) weeks, 23 (18-28) weeks, and 32 (21-37) weeks, respectively. To improve the visualisation, in three cases amnio-exchange was undertaken; the procedure was abandoned in two due to poor visualisation. The overall fetal survival rate, the double infant survival rate, and survival rate for at least one twin were 72% (43/60), 60% (18/30), and 83% (25/30), respectively. The most common peri-operative complication was bleeding from the uterine wall into the amniotic cavity, which affected three (10%) patients.
Our results of fetoscopic laser surgery for twin-twin transfusion syndrome were similar to those in specialised centres in other countries.
回顾接受胎儿镜激光凝固术治疗的双胎输血综合征的围产结局。
回顾性研究。
中国香港一所大学教学医院。
在单一中心接受胎儿镜胎盘吻合处激光凝固术治疗的 30 例双胎输血综合征连续病例。
手术并发症和围产儿存活率。
首次就诊、激光凝固术和分娩的中位孕龄分别为 22（16-27）周、23（18-28）周和 32（21-37）周。为改善可视化效果，在 3 例病例中进行了羊水交换；由于可视化效果不佳，有 2 例病例放弃了该操作。总的胎儿存活率、双胎存活率和至少存活 1 个胎儿的存活率分别为 72%（43/60）、60%（18/30）和 83%（25/30）。最常见的围手术期并发症是子宫壁出血进入羊膜腔，影响了 3 例（10%）患者。
我们对双胎输血综合征进行胎儿镜激光手术的结果与其他国家专门中心的结果相似。
