Abstract

Objective: To evaluate the outcome of radiofrequency ablation of the umbilical cord in the reduction of Twin Reversed Arterial Perfusion (TRAP) sequence or acardiac twin in monochorionic diamniotic pregnancies. Material and methods: In this prospective study, 25 cases of monochorionic diamniotic pregnancy with one acardiac twin underwent selected reduction using radiofrequency ablation (RFA) in the second trimester of gestational age, from 2018 to 2019 in a tertiary referral hospital affiliated to Tehran University of Medical Sciences. Results: The overall survival rate was 84%. The mean±SD of gestational age at the time of the procedure and delivery were 20.0±3.8 and 35w±6.0 days respectively. Nine neonates were admitted to the neonatal intensive care unit (NICU) and 4 miscarriages were recorded in less than 24 weeks. The procedures in all cases were technically successful in achieving selective termination. Conclusion: Radiofrequency ablation for fetal reduction in acardiac twins in monochorionic pregnancies appears to be a safe and reasonable option.

射频消融脐带减少双动脉灌注序列反转:一个病例系列

目的:探讨单绒毛膜双羊膜妊娠中脐带射频消融术降低双胎动脉灌注逆转(TRAP)序列或双心双胎的效果。材料和方法:在这项前瞻性研究中，2018年至2019年，德黑兰医科大学附属三级转诊医院的25例单绒毛膜双羊膜妊娠(1个心脏双胞胎)在妊娠中期采用射频消融术(RFA)选择性降低。结果:总生存率为84%。手术和分娩时胎龄的平均值±SD分别为20.0±3.8天和35w±6.0天。9名新生儿入住新生儿重症监护病房(NICU)，在不到24周的时间内记录了4例流产。所有病例的手术在技术上都成功地实现了选择性终止。结论:单绒毛膜妊娠的双心双胞胎采用射频消融术胎儿复位是一种安全合理的选择。
